As usual, + these changes affect UTC offsets in pre-1970 time stamps only. + Their old contents have been moved to the 'backzone' file. + The affected zones are: Africa/Bangui, Africa/Brazzaville, + Africa/Douala, Africa/Kinshasa, Africa/Libreville, Africa/Luanda, + Africa/Malabo, Africa/Niamey, and Africa/Porto-Novo. + + Changes affecting code + + Unless NETBSD_INSPIRED is defined to 0, the tz library now + supplies functions for creating and using objects that represent + time zones. The new functions are tzalloc, tzfree, localtime_rz, + mktime_z, and (if STD_INSPIRED is also defined) posix2time_z and + time2posix_z. They are intended for performance: for example, + localtime_rz (unlike localtime_r) is trivially thread-safe without + locking. (Thanks to Christos Zoulas for proposing NetBSD-inspired + functions, and to Alan Barrett and Jonathan Lennox for helping to + debug the change.) + + zdump now builds with the tz library unless USE_LTZ is defined to 0, + This lets zdump use tz features even if the system library lacks them. + To build zdump with the system library, use 'make CFLAGS=-DUSE_LTZ=0 + TZDOBJS=zdump.o CHECK_TIME_T_ALTERNATIVES='. + + zdump now uses localtime_rz if available, as it's significantly faster, + and it can help zdump better diagnose invalid time zone names. + Define HAVE_LOCALTIME_RZ to 0 to suppress this. HAVE_LOCALTIME_RZ + defaults to 1 if NETBSD_INSPIRED && USE_LTZ. When localtime_rz is + not available, zdump now uses localtime_r and tzset if available, + as this is a bit cleaner and faster than plain localtime. Compile + with -DHAVE_LOCALTIME_R=0 and/or -DHAVE_TZSET=0 if your system + lacks these two functions. + + If THREAD_SAFE is defined to 1, the tz library is now thread-safe. + Although not needed for tz's own applications, which are single-threaded, + this supports POSIX better if the tz library is used in multithreaded apps. + + Some crashes have been fixed when zdump or the tz library is given + invalid or outlandish input. + + The tz library no longer mishandles leap seconds on platforms with + unsigned time_t in time zones that lack ordinary transitions after 1970. + + The tz code now attempts to infer TM_GMTOFF and TM_ZONE if not + already defined, to make it easier to configure on common platforms. + Define NO_TM_GMTOFF and NO_TM_ZONE to suppress this. + + Unless the new macro UNINIT_TRAP is defined to 1, the tz code now + assumes that reading uninitialized memory yields garbage values + but does not cause other problems such as traps. + + If TM_GMTOFF is defined and UNINIT_TRAP is 0, mktime is now + more likely to guess right for ambiguous time stamps near + transitions where tm_isdst does not change. + + If HAVE_STRFTIME_L is defined to 1, the tz library now defines + strftime_l for compatibility with recent versions of POSIX. + Only the C locale is supported, though.

Standard Time of the Country (Japan) was adopted on Jan 1, 1888, using +# the time at 135E (GMT+9) +# +# 2. Standard Time of the Country was renamed to Central Standard Time, on Jan +# 1, 1898, and on the same day, the new territories Taiwan and Penghu islands, +# as well as Yaeyama and Miyako islands, adopted a new time zone called +# Western Standard Time, which is in GMT+8. +# +# 3. Western Standard Time was deprecated on Sep 30, 1937.

We have other instances of ambiguity -# (e.g. "IST" denoting both "Israel Standard Time" and "Indian -# Standard Time"), and they are not likely to go away any time soon. -# In the old days, some software mistakenly relied on unique -# abbreviations, but this is becoming less true with time, and I don't -# think it's that important to cater to such software these days. -# -# On the other hand, there is another motivation for unambiguous -# abbreviations: it cuts down on human confusion. This is -# particularly true for Australia, where "EST" can mean one thing for -# time T and a different thing for time T plus 1 second. -# -# * Does the relevant legislation indicate which abbreviations should be used? -# -# Here I tend to think that things are a mess, just as they are in -# many other countries. We Americans are currently disagreeing about -# which abbreviation to use for the newly legislated Chamorro Standard -# Time, for example. -# -# Personally, I would prefer to use common practice; I would like to -# refer to legislation only for examples of common practice, or as a -# tiebreaker. -# -# * Do Australians more often use "Eastern Daylight Time" or "Eastern -# Summer Time"? Do they typically prefix the time zone names with -# the word "Australian"? -# -# My own impression is that both "Daylight Time" and "Summer Time" are -# common and are widely understood, but that "Summer Time" is more -# popular; and that the leading "A" is also common but is omitted more -# often than not. I just used AltaVista advanced search and got the -# following count of page hits: -# -# 1,103 "Eastern Summer Time" AND domain:au -# 971 "Australian Eastern Summer Time" AND domain:au -# 613 "Eastern Daylight Time" AND domain:au -# 127 "Australian Eastern Daylight Time" AND domain:au -# -# Here "Summer" seems quite a bit more popular than "Daylight", -# particularly when we know the time zone is Australian and not US, -# say. The "Australian" prefix seems to be popular for Eastern Summer -# Time, but unpopular for Eastern Daylight Time. -# -# For abbreviations, tools like AltaVista are less useful because of -# ambiguity.

I also looked for pages +# mentioning both "western standard time" and an abbreviation, since +# there is no WST in the US to generate false hits, and found: +# +# 156 "western standard time" AWST site:au +# 226 "western standard time" WST site:au +# +# I then surveyed the top ten newspapers in Australia by circulation as +# listed in Wikipedia, using Google queries like "AEDT site:heraldsun.com.au" +# and obtaining estimated counts from the initial page of search results. +# All ten papers greatly preferred "AEDT" to "EDT". The papers +# surveyed were the Herald Sun, The Daily Telegraph, The Courier-Mail, +# The Sydney Morning Herald, The West Australian, The Age, The Advertiser, +# The Australian, The Financial Review, and The Herald (Newcastle). +# +# I also searched for historical usage, to see whether abbreviations +# like "AEDT" are new. A Trove search <http://trove.nla.gov.au/> +# found only one newspaper (The Canberra Times) with a house style +# dating back to the 1970s, I expect because other newspapers weren't +# fully indexed. The Canberra Times strongly preferred abbreviations +# like "AEDT". The first occurrence of "AEDT" was a World Weather +# column (1971-11-17, page 24), and of "ACDT" was a Scoreboard column +# (1993-01-24, p 16). The style was the typical usage but was not +# strictly enforced; for example, "Welcome to the twilight zones ..." +# (1994-10-29, p 1) uses the abbreviations AEST/AEDT, CST/CDT, and +# WST, and goes on to say, "The confusion and frustration some feel +# about the lack of uniformity among Australia's six states and two +# territories has prompted one group to form its very own political +# party -- the Sydney-based Daylight Saving Extension Party." +# +# I also surveyed federal government sources.
