Simplify timezone-handling code per proposal to pghackers: get rid of setting timezone-related variables during transaction start. They were not used anyway in platforms that HAVE_TM_ZONE or HAVE_INT_TIMEZONE, which it appears is *all* the platforms we are currently supporting. For platforms that have neither, we now only support UTC or numeric- offset-from-UTC timezones.

Transform all datetime and timespan catalog entries into new types. Make "INTERVAL" reserved word allowed as a column identifier in gram.y. Remove dt.h, dt.c files, and retarget datetime.h, datetime.c as utility routines for all date/time types. date.{h,c} now deals with date, time types. timestamp.{h,c} now deals with timestamp, interval types. nabstime.{h,c} now deals with abstime, reltime, tinterval types.

Adjust our timezone library to use pg_time_t (typedef'd as int64) in place of time_t, as per prior discussion. The behavior does not change on machines without a 64-bit-int type, but on machines with one, which is most, we are rid of the bizarre boundary behavior at the edges of the 32-bit-time_t range (1901 and 2038). The system will now treat times over the full supported timestamp range as being in your local time zone. It may seem a little bizarre to consider that times in 4000 BC are PST or EST, but this is surely at least as reasonable as propagating Gregorian calendar rules back that far. I did not modify the format of the zic timezone database files, which means that for the moment the system will not know about daylight-savings periods outside the range 1901-2038. Given the way the files are set up, it's not a simple decision like 'widen to 64 bits'; we have to actually think about the range of years that need to be supported. We should probably inquire what the plans of the upstream zic people are before making any decisions of our own.

From: Thomas Lockhart <Thomas.G.Lockhart@jpl.nasa.gov> Subject: [HACKERS] More date time functions Here are some additional patches mostly related to the date and time data types. It includes some type conversion routines to move between the different date types and some other date manipulation routines such as date_part(units,datetime). I noticed Edmund Mergl et al's neat trick for getting function overloading for builtin functions, so started to use that for the date and time stuff. Later, if someone figures out how to get function overloading directly for internal C code, then we can move to that technique. These patches include documentation updates (don't faint!) for the built-in man page. Doesn't yet include mention of timestamp, since I don't know much about it and since it may change a bit to become a _real_ ANSI timestamp which would include parser support for the declaration syntax (what do you think, Dan?). The patches were developed on the 970330 release, but have been rebuilt off of the 970402 release. The first patch below is to get libpq to compile, on my Linux box, but is not related to the rest of the patches and you can choose not to apply that one at this time. Thanks in advance, scrappy!

Allow now() and timestamp 'now' to use this higher precision result so we now have fractional seconds in this "constant". Add timestamp without time zone type. Move previous timestamp type to timestamp with time zone. Accept another ISO variant for date/time values: yyyy-mm-ddThh:mm:ss (note the "T" separating the day from hours information). Remove 'current' from date/time types; convert to 'now' in input. Separate time and timetz regression tests. Separate timestamp and timestamptz regression test.

Simplify timezone-handling code per proposal to pghackers: get rid of setting timezone-related variables during transaction start. They were not used anyway in platforms that HAVE_TM_ZONE or HAVE_INT_TIMEZONE, which it appears is *all* the platforms we are currently supporting. For platforms that have neither, we now only support UTC or numeric- offset-from-UTC timezones.

/* Note: don't pass NULL tzp to abstime2tm; affects behavior */
Fix timestamptz_in so that parsing of 'now'::timestamptz gives right answer when SET TIMEZONE has been done since the start of the current transaction. Per bug report from Robert Haas. I plan some futher cleanup in HEAD, but this is a low-risk patch for the immediate issue in 7.3.

Support alternate storage scheme of 64-bit integer for date/time types. Use "--enable-integer-datetimes" in configuration to use this rather than the original float8 storage. I would recommend the integer-based storage for any platform on which it is available. We perhaps should make this the default for the production release. Change timezone(timestamptz) results to return timestamp rather than a character string. Formerly, we didn't have a way to represent timestamps with an explicit time zone other than freezing the info into a string. Now, we can reasonably omit the explicit time zone from the result and return a timestamp with values appropriate for the specified time zone. Much cleaner, and if you need the time zone in the result you can put it into a character string pretty easily anyway. Allow fractional seconds in date/time types even for dates prior to 1BC. Limit timestamp data types to 6 decimal places of precision. Just right for a micro-second storage of int8 date/time types, and reduces the number of places ad-hoc rounding was occuring for the float8-based types. Use lookup tables for precision/rounding calculations for timestamp and interval types. Formerly used pow() to calculate the desired value but with a more limited range there is no reason to not type in a lookup table. Should be *much* better performance, though formerly there were some optimizations to help minimize the number of times pow() was called. Define a HAVE_INT64_TIMESTAMP variable. Based on the configure option "--enable-integer-datetimes" and the existing internal INT64_IS_BUSTED. Add explicit date/interval operators and functions for addition and subtraction. Formerly relied on implicit type promotion from date to timestamp with time zone. Change timezone conversion functions for the timetz type from "timetz()" to "timezone()". This is consistant with other time zone coersion functions for other types. Bump the catalog version to 200204201. Fix up regression tests to reflect changes in fractional seconds representation for date/times in BC eras. All regression tests pass on my Linux box.

From: Thomas Lockhart <Thomas.G.Lockhart@jpl.nasa.gov> Subject: [HACKERS] More date time functions Here are some additional patches mostly related to the date and time data types. It includes some type conversion routines to move between the different date types and some other date manipulation routines such as date_part(units,datetime). I noticed Edmund Mergl et al's neat trick for getting function overloading for builtin functions, so started to use that for the date and time stuff. Later, if someone figures out how to get function overloading directly for internal C code, then we can move to that technique. These patches include documentation updates (don't faint!) for the built-in man page. Doesn't yet include mention of timestamp, since I don't know much about it and since it may change a bit to become a _real_ ANSI timestamp which would include parser support for the declaration syntax (what do you think, Dan?). The patches were developed on the 970330 release, but have been rebuilt off of the 970402 release. The first patch below is to get libpq to compile, on my Linux box, but is not related to the rest of the patches and you can choose not to apply that one at this time. Thanks in advance, scrappy!

Adjust our timezone library to use pg_time_t (typedef'd as int64) in place of time_t, as per prior discussion. The behavior does not change on machines without a 64-bit-int type, but on machines with one, which is most, we are rid of the bizarre boundary behavior at the edges of the 32-bit-time_t range (1901 and 2038). The system will now treat times over the full supported timestamp range as being in your local time zone. It may seem a little bizarre to consider that times in 4000 BC are PST or EST, but this is surely at least as reasonable as propagating Gregorian calendar rules back that far. I did not modify the format of the zic timezone database files, which means that for the moment the system will not know about daylight-savings periods outside the range 1901-2038. Given the way the files are set up, it's not a simple decision like 'widen to 64 bits'; we have to actually think about the range of years that need to be supported. We should probably inquire what the plans of the upstream zic people are before making any decisions of our own.

Simplify timezone-handling code per proposal to pghackers: get rid of setting timezone-related variables during transaction start.

For platforms that have neither, we now only support UTC or numeric- offset-from-UTC timezones.

AbsoluteTime result;
Support alternate storage scheme of 64-bit integer for date/time types. Use "--enable-integer-datetimes" in configuration to use this rather than the original float8 storage. I would recommend the integer-based storage for any platform on which it is available. We perhaps should make this the default for the production release. Change timezone(timestamptz) results to return timestamp rather than a character string. Formerly, we didn't have a way to represent timestamps with an explicit time zone other than freezing the info into a string. Now, we can reasonably omit the explicit time zone from the result and return a timestamp with values appropriate for the specified time zone. Much cleaner, and if you need the time zone in the result you can put it into a character string pretty easily anyway. Allow fractional seconds in date/time types even for dates prior to 1BC. Limit timestamp data types to 6 decimal places of precision. Just right for a micro-second storage of int8 date/time types, and reduces the number of places ad-hoc rounding was occuring for the float8-based types. Use lookup tables for precision/rounding calculations for timestamp and interval types. Formerly used pow() to calculate the desired value but with a more limited range there is no reason to not type in a lookup table. Should be *much* better performance, though formerly there were some optimizations to help minimize the number of times pow() was called. Define a HAVE_INT64_TIMESTAMP variable. Based on the configure option "--enable-integer-datetimes" and the existing internal INT64_IS_BUSTED. Add explicit date/interval operators and functions for addition and subtraction. Formerly relied on implicit type promotion from date to timestamp with time zone. Change timezone conversion functions for the timetz type from "timetz()" to "timezone()". This is consistant with other time zone coersion functions for other types. Bump the catalog version to 200204201. Fix up regression tests to reflect changes in fractional seconds representation for date/times in BC eras. All regression tests pass on my Linux box.

Add guard code to protect from buffer overruns on long date/time input strings. Should go back in and look at doing this a bit more elegantly and (hopefully) cheaper. Probably not too bad anyway, but it seems a shame to scan the strings twice: once for length for this buffer overrun protection, and once to parse the line. Remove use of pow() in date/time handling; was already gone from everything *but* the time data types. Define macros for handling typmod manipulation for date/time types. Should be more robust than all of that brute-force inline code. Rename macros for masking and typmod manipulation to put TIMESTAMP_ or INTERVAL_ in front of the macro name, to reduce the possibility of name space collisions.

Accept an INTERVAL argument for SET TIME ZONE per SQL99. Modified the parser and the SET handlers to use full Node structures rather than simply a character string argument. Implement INTERVAL() YEAR TO MONTH (etc) syntax per SQL99. Does not yet accept the goofy string format that goes along with, but this should be fairly straight forward to fix now as a bug or later as a feature. Implement precision for the INTERVAL() type. Use the typmod mechanism for both of INTERVAL features. Fix the INTERVAL syntax in the parser: opt_interval was in the wrong place. INTERVAL is now a reserved word, otherwise we get reduce/reduce errors. Implement an explicit date_part() function for TIMETZ. Should fix coersion problem with INTERVAL reported by Peter E. Fix up some error messages for date/time types. Use all caps for type names within message. Fix recently introduced side-effect bug disabling 'epoch' as a recognized field for date_part() etc. Reported by Peter E. (??) Bump catalog version number.

From: Thomas Lockhart <Thomas.G.Lockhart@jpl.nasa.gov> Subject: [HACKERS] More date time functions Here are some additional patches mostly related to the date and time data types. It includes some type conversion routines to move between the different date types and some other date manipulation routines such as date_part(units,datetime). I noticed Edmund Mergl et al's neat trick for getting function overloading for builtin functions, so started to use that for the date and time stuff. Later, if someone figures out how to get function overloading directly for internal C code, then we can move to that technique. These patches include documentation updates (don't faint!) for the built-in man page. Doesn't yet include mention of timestamp, since I don't know much about it and since it may change a bit to become a _real_ ANSI timestamp which would include parser support for the declaration syntax (what do you think, Dan?). The patches were developed on the 970330 release, but have been rebuilt off of the 970402 release. The first patch below is to get libpq to compile, on my Linux box, but is not related to the rest of the patches and you can choose not to apply that one at this time. Thanks in advance, scrappy!

AbsoluteTime result;
Support alternate storage scheme of 64-bit integer for date/time types. Use "--enable-integer-datetimes" in configuration to use this rather than the original float8 storage. I would recommend the integer-based storage for any platform on which it is available. We perhaps should make this the default for the production release. Change timezone(timestamptz) results to return timestamp rather than a character string. Formerly, we didn't have a way to represent timestamps with an explicit time zone other than freezing the info into a string. Now, we can reasonably omit the explicit time zone from the result and return a timestamp with values appropriate for the specified time zone. Much cleaner, and if you need the time zone in the result you can put it into a character string pretty easily anyway. Allow fractional seconds in date/time types even for dates prior to 1BC. Limit timestamp data types to 6 decimal places of precision. Just right for a micro-second storage of int8 date/time types, and reduces the number of places ad-hoc rounding was occuring for the float8-based types. Use lookup tables for precision/rounding calculations for timestamp and interval types. Formerly used pow() to calculate the desired value but with a more limited range there is no reason to not type in a lookup table. Should be *much* better performance, though formerly there were some optimizations to help minimize the number of times pow() was called. Define a HAVE_INT64_TIMESTAMP variable. Based on the configure option "--enable-integer-datetimes" and the existing internal INT64_IS_BUSTED. Add explicit date/interval operators and functions for addition and subtraction. Formerly relied on implicit type promotion from date to timestamp with time zone. Change timezone conversion functions for the timetz type from "timetz()" to "timezone()". This is consistant with other time zone coersion functions for other types. Bump the catalog version to 200204201. Fix up regression tests to reflect changes in fractional seconds representation for date/times in BC eras. All regression tests pass on my Linux box.

Remove dt.h, dt.c files, and retarget datetime.h, datetime.c as utility routines for all date/time types. date.{h,c} now deals with date, time types. timestamp.{h,c} now deals with timestamp, interval types. nabstime.{h,c} now deals with abstime, reltime, tinterval types.

From: Thomas Lockhart <Thomas.G.Lockhart@jpl.nasa.gov> Subject: [HACKERS] More date time functions Here are some additional patches mostly related to the date and time data types. It includes some type conversion routines to move between the different date types and some other date manipulation routines such as date_part(units,datetime). I noticed Edmund Mergl et al's neat trick for getting function overloading for builtin functions, so started to use that for the date and time stuff. Later, if someone figures out how to get function overloading directly for internal C code, then we can move to that technique. These patches include documentation updates (don't faint!) for the built-in man page. Doesn't yet include mention of timestamp, since I don't know much about it and since it may change a bit to become a _real_ ANSI timestamp which would include parser support for the declaration syntax (what do you think, Dan?). The patches were developed on the 970330 release, but have been rebuilt off of the 970402 release. The first patch below is to get libpq to compile, on my Linux box, but is not related to the rest of the patches and you can choose not to apply that one at this time. Thanks in advance, scrappy!

Measure the current transaction time to milliseconds. Define a new function, GetCurrentTransactionStartTimeUsec() to get the time to this precision. Allow now() and timestamp 'now' to use this higher precision result so we now have fractional seconds in this "constant". Add timestamp without time zone type. Move previous timestamp type to timestamp with time zone. Accept another ISO variant for date/time values: yyyy-mm-ddThh:mm:ss (note the "T" separating the day from hours information). Remove 'current' from date/time types; convert to 'now' in input. Separate time and timetz regression tests. Separate timestamp and timestamptz regression test.

AbsoluteTime result;
Support alternate storage scheme of 64-bit integer for date/time types. Use "--enable-integer-datetimes" in configuration to use this rather than the original float8 storage. I would recommend the integer-based storage for any platform on which it is available. We perhaps should make this the default for the production release. Change timezone(timestamptz) results to return timestamp rather than a character string. Formerly, we didn't have a way to represent timestamps with an explicit time zone other than freezing the info into a string. Now, we can reasonably omit the explicit time zone from the result and return a timestamp with values appropriate for the specified time zone. Much cleaner, and if you need the time zone in the result you can put it into a character string pretty easily anyway. Allow fractional seconds in date/time types even for dates prior to 1BC. Limit timestamp data types to 6 decimal places of precision. Just right for a micro-second storage of int8 date/time types, and reduces the number of places ad-hoc rounding was occuring for the float8-based types. Use lookup tables for precision/rounding calculations for timestamp and interval types. Formerly used pow() to calculate the desired value but with a more limited range there is no reason to not type in a lookup table. Should be *much* better performance, though formerly there were some optimizations to help minimize the number of times pow() was called. Define a HAVE_INT64_TIMESTAMP variable. Based on the configure option "--enable-integer-datetimes" and the existing internal INT64_IS_BUSTED. Add explicit date/interval operators and functions for addition and subtraction. Formerly relied on implicit type promotion from date to timestamp with time zone. Change timezone conversion functions for the timetz type from "timetz()" to "timezone()". This is consistant with other time zone coersion functions for other types. Bump the catalog version to 200204201. Fix up regression tests to reflect changes in fractional seconds representation for date/times in BC eras. All regression tests pass on my Linux box.

reltime2tm(time, tm);
Support alternate storage scheme of 64-bit integer for date/time types. Use "--enable-integer-datetimes" in configuration to use this rather than the original float8 storage. I would recommend the integer-based storage for any platform on which it is available. We perhaps should make this the default for the production release. Change timezone(timestamptz) results to return timestamp rather than a character string. Formerly, we didn't have a way to represent timestamps with an explicit time zone other than freezing the info into a string. Now, we can reasonably omit the explicit time zone from the result and return a timestamp with values appropriate for the specified time zone. Much cleaner, and if you need the time zone in the result you can put it into a character string pretty easily anyway. Allow fractional seconds in date/time types even for dates prior to 1BC. Limit timestamp data types to 6 decimal places of precision. Just right for a micro-second storage of int8 date/time types, and reduces the number of places ad-hoc rounding was occuring for the float8-based types. Use lookup tables for precision/rounding calculations for timestamp and interval types. Formerly used pow() to calculate the desired value but with a more limited range there is no reason to not type in a lookup table. Should be *much* better performance, though formerly there were some optimizations to help minimize the number of times pow() was called. Define a HAVE_INT64_TIMESTAMP variable. Based on the configure option "--enable-integer-datetimes" and the existing internal INT64_IS_BUSTED. Add explicit date/interval operators and functions for addition and subtraction. Formerly relied on implicit type promotion from date to timestamp with time zone. Change timezone conversion functions for the timetz type from "timetz()" to "timezone()". This is consistant with other time zone coersion functions for other types. Bump the catalog version to 200204201. Fix up regression tests to reflect changes in fractional seconds representation for date/times in BC eras. All regression tests pass on my Linux box.

Create a 'type cache' that keeps track of the data needed for any particular datatype by array_eq and array_cmp; use this to solve problems with memory leaks in array indexing support. The parser's equality_oper and ordering_oper routines also use the cache. Change the operator search algorithms to look for appropriate btree or hash index opclasses, instead of assuming operators named '<' or '=' have the right semantics. (ORDER BY ASC/DESC now also look at opclasses, instead of assuming '<' and '>' are the right things.) Add several more index opclasses so that there is no regression in functionality for base datatypes. initdb forced due to catalog additions.

Support alternate storage scheme of 64-bit integer for date/time types. Use "--enable-integer-datetimes" in configuration to use this rather than the original float8 storage. I would recommend the integer-based storage for any platform on which it is available. We perhaps should make this the default for the production release. Change timezone(timestamptz) results to return timestamp rather than a character string. Formerly, we didn't have a way to represent timestamps with an explicit time zone other than freezing the info into a string. Now, we can reasonably omit the explicit time zone from the result and return a timestamp with values appropriate for the specified time zone. Much cleaner, and if you need the time zone in the result you can put it into a character string pretty easily anyway. Allow fractional seconds in date/time types even for dates prior to 1BC. Limit timestamp data types to 6 decimal places of precision. Just right for a micro-second storage of int8 date/time types, and reduces the number of places ad-hoc rounding was occuring for the float8-based types. Use lookup tables for precision/rounding calculations for timestamp and interval types. Formerly used pow() to calculate the desired value but with a more limited range there is no reason to not type in a lookup table. Should be *much* better performance, though formerly there were some optimizations to help minimize the number of times pow() was called. Define a HAVE_INT64_TIMESTAMP variable. Based on the configure option "--enable-integer-datetimes" and the existing internal INT64_IS_BUSTED. Add explicit date/interval operators and functions for addition and subtraction. Formerly relied on implicit type promotion from date to timestamp with time zone. Change timezone conversion functions for the timetz type from "timetz()" to "timezone()". This is consistant with other time zone coersion functions for other types. Bump the catalog version to 200204201. Fix up regression tests to reflect changes in fractional seconds representation for date/times in BC eras. All regression tests pass on my Linux box.

Support alternate storage scheme of 64-bit integer for date/time types. Use "--enable-integer-datetimes" in configuration to use this rather than the original float8 storage. I would recommend the integer-based storage for any platform on which it is available. We perhaps should make this the default for the production release. Change timezone(timestamptz) results to return timestamp rather than a character string. Formerly, we didn't have a way to represent timestamps with an explicit time zone other than freezing the info into a string. Now, we can reasonably omit the explicit time zone from the result and return a timestamp with values appropriate for the specified time zone. Much cleaner, and if you need the time zone in the result you can put it into a character string pretty easily anyway. Allow fractional seconds in date/time types even for dates prior to 1BC. Limit timestamp data types to 6 decimal places of precision. Just right for a micro-second storage of int8 date/time types, and reduces the number of places ad-hoc rounding was occuring for the float8-based types. Use lookup tables for precision/rounding calculations for timestamp and interval types. Formerly used pow() to calculate the desired value but with a more limited range there is no reason to not type in a lookup table. Should be *much* better performance, though formerly there were some optimizations to help minimize the number of times pow() was called. Define a HAVE_INT64_TIMESTAMP variable. Based on the configure option "--enable-integer-datetimes" and the existing internal INT64_IS_BUSTED. Add explicit date/interval operators and functions for addition and subtraction. Formerly relied on implicit type promotion from date to timestamp with time zone. Change timezone conversion functions for the timetz type from "timetz()" to "timezone()". This is consistant with other time zone coersion functions for other types. Bump the catalog version to 200204201. Fix up regression tests to reflect changes in fractional seconds representation for date/times in BC eras. All regression tests pass on my Linux box.

Measure the current transaction time to milliseconds. Define a new function, GetCurrentTransactionStartTimeUsec() to get the time to this precision. Allow now() and timestamp 'now' to use this higher precision result so we now have fractional seconds in this "constant". Add timestamp without time zone type. Move previous timestamp type to timestamp with time zone. Accept another ISO variant for date/time values: yyyy-mm-ddThh:mm:ss (note the "T" separating the day from hours information).

The parser's equality_oper and ordering_oper routines also use the cache. Change the operator search algorithms to look for appropriate btree or hash index opclasses, instead of assuming operators named '<' or '=' have the right semantics. (ORDER BY ASC/DESC now also look at opclasses, instead of assuming '<' and '>' are the right things.) Add several more index opclasses so that there is no regression in functionality for base datatypes. initdb forced due to catalog additions.

Implement "date/time grand unification". Transform datetime and timespan into timestamp and interval. Deprecate datetime and timespan, though translate to new types in gram.y. Transform all datetime and timespan catalog entries into new types. Make "INTERVAL" reserved word allowed as a column identifier in gram.y. Remove dt.h, dt.c files, and retarget datetime.h, datetime.c as utility routines for all date/time types. date.{h,c} now deals with date, time types. timestamp.{h,c} now deals with timestamp, interval types. nabstime.{h,c} now deals with abstime, reltime, tinterval types. Make NUMERIC a known native type for purposes of type coersion. Not tested.

Adjust our timezone library to use pg_time_t (typedef'd as int64) in place of time_t, as per prior discussion. The behavior does not change on machines without a 64-bit-int type, but on machines with one, which is most, we are rid of the bizarre boundary behavior at the edges of the 32-bit-time_t range (1901 and 2038). The system will now treat times over the full supported timestamp range as being in your local time zone. It may seem a little bizarre to consider that times in 4000 BC are PST or EST, but this is surely at least as reasonable as propagating Gregorian calendar rules back that far. I did not modify the format of the zic timezone database files, which means that for the moment the system will not know about daylight-savings periods outside the range 1901-2038. Given the way the files are set up, it's not a simple decision like 'widen to 64 bits'; we have to actually think about the range of years that need to be supported. We should probably inquire what the plans of the upstream zic people are before making any decisions of our own.
