"I put myself and my staff through this crazy, huge ordeal, all because I refused to go on at midnight, okay? And so I work, you know, and then I get this job at eleven, supposed to be a big deal. Then yesterday daylight savings [sic] time ended. Right now it's basically midnight." Conan O'Brien on the 2010-11-08 premier of "Conan."

by Alexander Krivenyshev Nov. 1, 2010

Nov. 1, 2010

According to the media from Brazil, during recent referendum state Acre rejected current time zone (GMT-4) and would like to return to old time zone (pre-2008) - GMT-5. The decision of Acre will be sent to the Congress to become law and to re-apply the old time.

Extension to tzcode to support additional timezones
by John Baldwin Oct. 27, 2010

Oct. 27, 2010

Several of my employers have needed to work with data from multiple timezones within a single process. The traditional way to work with this has been to change the value of the TZ environment variable and invoke tzset() and switch between timezones one at a time. What I have done is extend the time(3) API to allow applications to load and use arbitrary timezones separate from the current local and GM timezones. I've done this by adding the following API calls: - void *tzopen(const char *name). This loads the rules for a specified timezone and returns a void * cookie. If the zone cannot be parsed it returns NULL and sets errno to EINVAL. - void tzclose(void *zone). This "closes" a set of rules opened via tzopen() by releasing the associated resources. - struct tm *tztime(void *zone, const time_t *t, struct tm *tm). This is like localtime_r() except that it uses the timezone rules from the passed in cookie instead of the local timezone indicated by TZ. - time_t timetz(void *zone, struct tm * const tm). This is like mktime() except that it uses the timezone rules from the passed in cookie instead of the local timezone indicated by TZ. The changes to the code are fairly simple since the per-zone state was already broken out into a standalone state object to handle GMT vs local time. In some cases the patches make things cleaner (I think) by removing hacks where a function pointer was queried to determine which state object to use since the state object pointer is now passed all the way down the internal time code stack. I have a patch that is relative to the FreeBSD source tree, but all of the real code changes are in localtime.c which I believe should apply directly to the tzcode distribution. The patch is available at http://www.FreeBSD.org/~jhb/patches/tzopen.patch Is this API something that you folks would be interested in? I currently have this as a private patch locally, but if possible I would like it adopted upstream. -- John Baldwin

2010n
by Olson, Arthur David (NIH/NCI) [E] Oct. 25, 2010

Oct. 25, 2010

The files... ftp://elsie.nci.nih.gov/pub/tzcode2010n.tar.gz ...and... ftp://elsie.nci.nih.gov/pub/tzdata2010n.tar.gz ...are now available; these reflect the changes circulated on 2010-10-13 on the time zone mailing list. I expect that data2010o will appear on 2010-11-01 in light of the change in the end of DST in Fiji in 2011. Folks wanting to avoid version thrash may want to hold off for a week. --ado

Another China time zone question
by Jonathan Hassid Oct. 22, 2010

Oct. 22, 2010

Dear time zone list: I have been doing a little research on time zones in China, and one of the few sources on the matter seems to contradict the tz database. While the database indicates there were multiple time zones until 1980, Guo Qingheng of the Chinese Academy of Science Time Service Center published an article in 2003 in which he states that primary documents indicate that "probably in order to comply with instructions from central broadcasters, after liberation [that is, after 1949] the broadcasters in each area very quickly changed their local times to Beijing Time, in order to express unanimity with the center." And that "by the beginning of 1950, within a few months after establishing the country, the entire country except for Xinjiang and Tibet was all using the Beijing Time standard," with Tibet following in 1960 and Xinjiang by 1975 (Guo Qingsheng [郭庆生], "Beijing Time at the Beginning of the PRC [建国初期的北京时间]." The Chinese Journal for the History of Science and Technology [中国科技史料]. Vol. 24, No. 1, (2003), p2.) So I was wondering what the sources are for China having multiple time zones from 1949-1980, and who is correct here. Any help is appreciated!
