Thomas G. Lockhart 93ac35f06c Fix a few DATEDEBUG print statements. 1997-06-03 13:56:32 +00:00
Thomas G. Lockhart 43b6f1e678 Clean up support for USE_POSIX_TIME, ! HAVE_INT_TIMEZONE machines.
Remove references to modf() which is buggy on some platforms (Sparc/Linux).

Thomas G. Lockhart e35b759fed Fix datetime and abstime conversions to and from date.
Bring optional new-storage date and time up to date and test.
This new storage format should fix the "Sparc gcc -O2 bug".
(Enable new code with USE_NEW_DATE and USE_NEW_TIME in dt.h)

Thomas G. Lockhart 64d9b50893 Fix timezone manipulation code to avoid crashes on some machines.
Add type conversion functions for floating point numbers.
Check for zero in unary minus floating point code (IEEE allows an
 explicit negative zero which looks ugly in a query result!).
Ensure circle type has non-negative radius.

Subject: [HACKERS] Patch: set date to euro/us postgres/iso/sql

  Here a patch that implements a SET date for use by the datetime
stuff. The syntax is

        SET date TO 'val[,val,...]'

  where val is us (us dates), euro (european dates), postgres,
iso or sql.

  Thomas is working on the integration in his datetime module.
I just needed to get the patch out before it went stale :)

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!
