Replace raw timezone source data with IANA's new compact format.
Traditionally IANA has distributed their timezone data in pure source form, replete with extensive historical comments. As of release 2017c, they've added a compact single-file format that omits comments and abbreviates command keywords. This form is way shorter than the pure source, even before considering its allegedly better compressibility. Hence, let's distribute the data in that form rather than pure source. I'm pushing this now, rather than at the next timezone database update, so that it's easy to confirm that this data file produces compiled zic output that's identical to what we were getting before.

Time Zone data
|

==============
|
||||
|
||||
The data files under data/ are an exact copy of the latest tzdata set,
|
||||
except that we omit some files that are not of interest for our purposes.
|
||||
We distribute the time zone source data as-is under src/timezone/data/.
|
||||
Currently, we distribute just the abbreviated single-file format
|
||||
"tzdata.zi", to reduce the size of our tarballs as well as churn
|
||||
in our git repo. Feeding that file to zic produces the same compiled
|
||||
output as feeding the bulkier individual data files would do.
|
||||
|
||||
While the files under data/ can just be duplicated when updating, manual
|
||||
effort is needed to update the time zone abbreviation lists under tznames/.

# solar noon. So the Vostok time might have been whatever the clocks

#
|
||||
# From Chris Carrier (1996-06-27):
|
||||
# Siple, the first commander of the South Pole station,
|
||||
# stated that he would have liked to have kept GMT at the station,
|
||||
# but that he found it more convenient to keep GMT+12
|
||||
# as supplies for the station were coming from McMurdo Sound,
|
||||
# which was on GMT+12 because New Zealand was on GMT+12 all year
|
||||
# at that time (1957). (Source: Siple's book 90 Degrees South.)
|
||||
#
|
||||
# From Susan Smith

||||
# http://www.cybertours.com/whs/pole10.html
|
||||
# (1995-11-13 16:24:56 +1300, no longer available):
|
||||
# We use the same time as McMurdo does.
|
||||
# And they use the same time as Christchurch, NZ does....
|
||||
# One last quirk about South Pole time.
|
||||
# All the electric clocks are usually wrong.
|
||||
# Something about the generators running at 60.1hertz or something
|
||||
# makes all of the clocks run fast. So every couple of days,
|
||||
# we have to go around and set them back 5 minutes or so.
|
||||
# Maybe if we let them run fast all of the time, we'd get to leave here sooner!!

# This file is in the public domain.

# This file is by no means authoritative; if you think you know

# better, go ahead and edit it (and please send any changes to

# the file CONTRIBUTING in the tz distribution.
|
||||
|

|

# From Paul Eggert (2014-10-31):
|
||||
|
||||
# This file contains data outside the normal scope of the tz database,
|
||||
# in that its zones do not differ from normal tz zones after 1970.
|
||||
# Links in this file point to zones in this file, superseding links in
|
||||
# the file 'backward'.
|
||||
|
||||
# Although zones in this file may be of some use for analyzing
|
||||
# pre-1970 time stamps, they are less reliable, cover only a tiny
|
||||
# sliver of the pre-1970 era, and cannot feasibly be improved to cover
|
||||
# most of the era. Because the zones are out of normal scope for the
|
||||
# database, less effort is put into maintaining this file. Many of
|
||||
# the zones were formerly in other source files, but were removed or
|
||||
# replaced by links as their data entries were questionable and/or they
|
||||
# differed from other zones only in pre-1970 time stamps.
|
||||
|
||||
# Unless otherwise specified, the source for data through 1990 is:
|
||||
# Thomas G. Shanks and Rique Pottenger, The International Atlas (6th edition),
|
||||
# San Diego: ACS Publications, Inc. (2003).
|
||||
# Unfortunately this book contains many errors and cites no sources.

# This file is not intended to be compiled standalone, as it

# Ethiopia
|
||||
# From Paul Eggert (2014-07-31):
|
||||
# Like the Swahili of Kenya and Tanzania, many Ethiopians keep a
|
||||
# 12-hour clock starting at our 06:00, so their "8 o'clock" is our
|
||||
# 02:00 or 14:00. Keep this in mind when you ask the time in Amharic.
|
||||
#
|
||||
# Shanks & Pottenger write that Ethiopia had six narrowly-spaced time
|
||||
# zones between 1870 and 1890, that they merged to 38E50 (2:35:20) in
|
||||
# 1890, and that they switched to 3:00 on 1936-05-05. Perhaps 38E50
|
||||
# was for Adis Dera. Quite likely the Shanks data entries are wrong
|
||||
# anyway.

# Westminster. There is a little uncertainty as to the starting date

# of the first summer time in 1916 which may have been announced a

# On 1989-04-05, the U. S. House of Representatives passed (238-154) a bill
|

# establishing "Pacific Presidential Election Time"; it was not acted on

# by the Senate or signed into law by the President.
|

# You might want to change the "PE" (Presidential Election) below to

# "Q" (Quadrennial) to maintain three-character zone abbreviations.
|
||||
# If you're really conservative, you might want to change it to "D".
|
||||
# Avoid "L" (Leap Year), which won't be true in 2100.
|

|

# If Presidential Election Time is ever established, replace "XXXX" below
