Bruce Momjian	bf831f6e9f	Back out timezone detection patch. Tom already applied it.	22 years ago
Bruce Momjian	525449be27	This patch attempts to fix the issue with localized timezones on ... Windows. Recap: When running on a localized windows version, the timezone name returned is also localized, and therefor does not match our lookup table. Solution: The registry contains both the name of the timezone in english and the localized name. The patch adds code to scan the registry for the localized name and gets the english name from that, and then rescans the table. I have tested this on a Swedish WinXP, and it works without problems. The registry layout is the same in Win2k, but I haven't specifically tested it. It's also the same on different languages but again only Swedish is tested. Magnus Hagander	22 years ago
Tom Lane	d1b2260cdc	Add code to be able to match the timezone name on localized Windows ... systems. Magnus Hagander.	22 years ago
Bruce Momjian	15d3f9f6b7	Another pgindent run with lib typedefs added.	22 years ago
Bruce Momjian	b6b71b85bc	Pgindent run for 8.0.	22 years ago
Bruce Momjian	da9a8649d8	Update copyright to 2004.	22 years ago
Tom Lane	178ec6f40e	Fix function definition that somehow missed being ANSI-fied, and align ... it with previous prototype to suppress complaints from picky compilers, per report from Scott Bailey. Also, remove substitute strerror definition --- not needed, since we link this with libpgport.	22 years ago
Bruce Momjian	8120ff636b	More Win32 zic build cleanups now that we have symlinks, it needs help.	22 years ago

Bruce Momjian	68993b650f	Link in dirmod specially for zic so it works on Win32.	22 years ago
Tom Lane	2def4552ed	Still another try at matching system timezone nicely. On non-Windows ... machines, break tie scores by preferring shorter zone names over longer; for names of equal length, prefer the alphabetically first name. This yields for example 'EST5EDT' not 'America/New_York' for US eastern time. On Windows, abandon the whole concept of inspecting the detailed behavior of the system TZ library, because it doesn't bear inspection :-(. Instead use a hardwired mapping table to select our zone name based on the result of strftime %Z output. Windows code from Magnus Hagander.	22 years ago
Tom Lane	94f8f63fdb	Must guard against NULL return from localtime() when probing pre-1970 ... dates. Per Magnus Hagander.	22 years ago
Tom Lane	e31c8cf20b	Still another try at automatically detecting the best match in the zic ... timezone database for the system behavior we find ourselves in. Scan backwards from current time and choose the zone that matches furthest back. As per discussion a week or so back.	22 years ago
Tom Lane	68938c4770	Add missing <getopt.h>, per Dann Corbit.	22 years ago
Tom Lane	99b225c528	Check more test points (in fact, every week in 1970..2004) to get a more ... accurate matching of our time zone to the system's zone. This method is able to distinguish Antarctica/Casey from Australia/Perth, as in Chris K-L's recent example; and it is not materially slower than before, because the extra checks generally don't get done against very many time zones. It seems possible that with this test we'd be able to correctly identify Windows timezones without looking at the timezone name, but I do not have the ability to try it.	22 years ago
Tom Lane	921d749bd4	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.	22 years ago
Tom Lane	37da0ba0e0	Seems we forgot the installdirs target in this makefile.	22 years ago
Tom Lane	bfb77c15ca	Tweaks per discussion with Magnus: suppress chatter on unpatched MinGW ... systems, add verbose logging (at DEBUG4) to help identify why a given time zone is not matched.	22 years ago
Tom Lane	76c50c080b	Add code to identify_system_timezone() to try all zones in the zic ... database, not just ones that we cons up POSIX names for. This looks grim but it seems to take less than a second even on a relatively slow machine, and since it only happens once during postmaster startup, that seems acceptable.	22 years ago
Tom Lane	dc39937762	Rewrite identify_system_timezone() to give it better-than-chance odds ... of correctly identifying the system's daylight-savings transition rules. This still begs the question of how to look through the zic database to find a matching zone definition, but at least now we'll have some chance of recognizing the match when we find it.	22 years ago
Tom Lane	17edb84056	Seems we had the wrong sign convention for the default Etc/GMTx zone ... names. Per report from Alvaro.	22 years ago
Tom Lane	f9df1b28e8	Use case-insensitive comparison so that explicitly setting timezone=unknown ... in postgresql.conf does the right thing. variable.c got this right, but not pgtz.c ...	22 years ago

Tom Lane	d584db6086	pgindent did a pretty awful job on the timezone code, particularly with ... respect to doubly-starred comment blocks. Do some manual cleanup.	22 years ago
Bruce Momjian	0a19fb42c2	Pgindent timezone file, per request from Tom.	22 years ago
Tom Lane	63bd0db121	Integrate src/timezone library for all platforms. There is more we can ... and should do now that we control our own destiny for timezone handling, but this commit gets the bulk of the picayune diffs in place. Magnus Hagander and Tom Lane.	22 years ago
Bruce Momjian	48eb73b556	Allow zic to compile by defining a "" value for my_exec_path. It isn't ... used by zic anyway.	22 years ago
