tzcode2007h.tar.gz - Functions defined with prototypes and C99 features?
by Jonathan Leffler Nov. 7, 2007

Nov. 7, 2007

In the tzcode2007h.tar.gz file, there is (at least) one function that is defined in prototype notation: static time_t hunt(char *name, time_t lot, time_t hit) It seems to me that the code assumes that there is a 64-bit integer type (int_fast64_t (function detzcode64()), though the code goes through some machinations to find a 64-bit integer and doesn't outright assume C99 compliance. Is there actually a good reason not to write the whole library with ISO prototypes? And lose the historically necessary but now unnecessary P macro for declaring functions with (or without) prototypes. Which platform(s) do not provide a C compiler that is capable of handling prototypes? I know of none on the major platforms...Unix, Linux, Windows (though maybe the bundled C compiler on HP-UX is still unaware, but that is intended for linking kernels, not program development). -- Jonathan Leffler <jonathan.leffler(a)gmail.com> #include <disclaimer.h> Guardian of DBD::Informix - v2007.0914 - http://dbi.perl.org "Blessed are we who can laugh at ourselves, for we shall never cease to be amused."

Re: Iran's exact law for re-instating daylight saving
by Paul Schauble Nov. 7, 2007

Nov. 7, 2007

I think there. Is an additional complication here. I believe the Persian calendar begins on the day of the true equinox. This varies over about a 2 day period so there is not a fixed correspondence between Persiam dates and Gregorian. I'm sure I will be corrected if need be. ++PLS ----- Original Message ----- From: Roozbeh Pournader <roozbeh(a)farsiweb.info> To: Paul Eggert <eggert(a)CS.UCLA.EDU> Cc: tz(a)lecserver.nci.nih.gov <tz(a)lecserver.nci.nih.gov> Sent: Wed Nov 07 05:09:15 2007 Subject: Re: Iran's exact law for re-instating daylight saving On Tue, 2007-11-06 at 00:27 -0800, Paul Eggert wrote: > Thanks for the citation.

The law is basically reinstating the 1991 regulation of President Rafsanjani's board of ministers which was canceled by President Ahmadinejad's board of ministers a few days before daylight saving was supposed to come into effect again in 2006. BTW, the funny thing is that Hassan Habibi, the First Vice President that signed the 1991 regulation, and Gholam Ali Haddad-Adel, the Parliament's Speaker who signed the 2007 one, have been the only two presidents of Iranian Academy of Persian Language and Literature since its revival in 1990. Habibi became the Academy's President when it was recreated (while also serving as First Vice President) and was replaced by Haddad-Adel after his term finished. But later, Haddad-Adel resigned from the post when he became the Parliament's Speaker, leading in Habibi filling his original position again. Roozbeh

proposed tz changes for Brazil, Egypt, Iran, Gaza, Venezuela
by Paul Eggert Nov. 7, 2007

Nov. 7, 2007

Here are proposed changes to the tz database for the news items we've accumulated recently: * Brazil will observe DST from 2007-10-14 00:00 to 2008-02-17 00:00. (Thanks to Steffen Thorsen for this.) * Egypt switched earlier than we expected. (Thanks to Dirk Losch and Jesper Norgaard Welen for this.) * Likewise for Gaza. (Thanks to Jesper Norgaard Welen for this.) * Iran will resume DST next year. (Thanks to Jesper Norgaard Welen for this.) * Venezuela is currently planning to change time zones on January 1, to -04:30. This seems to be a bit disorganized, but I suppose we can change the database later as needed. =================================================================== RCS file: RCS/africa,v retrieving revision 2007.7 retrieving revision 2007.7.0.1 diff -pu -r2007.7 -r2007.7.0.1 --- africa 2007/08/20 14:45:10 2007.7 +++ africa 2007/09/07 22:39:16 2007.7.0.1 @@ -224,9 +224,19 @@ Rule Egypt 2006 only - Sep 21 23:00s 0 - # From Jesper Norgaard Welen (2007-08-15): [The following agree:] # http://www.nentjes.info/Bill/bill5.htm # http://www.timeanddate.com/worldclock/city.html?n=53 +# From Steffen Thorsen (2007-09-04): The official information...: +# http://www.sis.gov.eg/En/EgyptOnline/Miscellaneous/000002/02070000000000000… +Rule Egypt 2007 only - Sep Thu>=1 23:00s 0 - +# From Abdelrahman Hassan (2007-09-06): +# Due to the Hijri (lunar Islamic calendar) year being 11 days shorter +# than the year of the Gregorian calendar, Ramadan shifts earlier each +# year.

FW: Australian time zone names
by Olson, Arthur David (NIH/NCI) [E] Nov. 2, 2007

Nov. 2, 2007

I'm forwarding this message from Mark Jerkovic, who is not on the time zone mailing list. Those of you who are on the time zone list should direct replies appropriately. --ado From: Mark Jerkovic [mailto:mjerkovic@aconex.com] Sent: Thursday, November 01, 2007 7:24 PM To: tz(a)lecserver.nci.nih.gov Subject: Australian time zone names Hi, I would like to propose an amendment to the format of Australian timezones. Currently the format is EST for eastern states and WST for western states. This is incorrect. The Australian Government defines time zone names as follows: Time Zones There are three times zones in Australia - Eastern Australian Eastern Standard Time (AEST) is equal to Greenwich Mean Time plus 10 hours (GMT +10). AEST is followed in these regions: • New South Wales (except Broken Hill) • Victoria • Queensland • Tasmania • Australian Capital Territory Central Australian Central Standard Time (ACST) is equal to Greenwich Mean Time plus 9 ½ hours (GMT +9 ½). ACST is followed in these regions: • South Australia • Northern Territory • Broken Hill, NSW Western Australian Western Standard Time (AWST) is equal to Greenwich Mean Time plus 8 hours (GMT +8). AWST is followed in these regions: • Western Australia Daylight Saving Daylight saving time is observed by New South Wales, Victoria, South Australia, Tasmania, and the Australian Capital Territory from early to late October to the end of March. Western Australia began a three year trial of daylight saving on 3 December 2006. Queensland and the Northern Territory do not observe daylight savings. Where daylight saving is being observed: • AEST becomes Australian Eastern Daylight Time (AEDT), and clocks are advanced to GMT +11. • ACST becomes Australian Central Daylight Time (ACDT), and clocks are advanced to GMT +10 ½. • AWST becomes Australian Western Daylight Time (AWDT), and clocks are advanced to GMT +9. The link where this came from is http://www.australia.gov.au/Time_Zones Could these naming conventions be added to the timezone database? Thanks, Mark.
