Chinese timezones 1970
by Jesper Norgaard Welen Sept. 14, 2008

Sept. 14, 2008

I have investigated the timezones around 1970 on the http://www.astro.com/atlas site, and here are the results. I am attaching a GIF file of the map I have built based on this information. The red borders are the modern-time administrative borders, while the green lines are the timezone borders I have determined, note that some of them are partially hidden behind the red lines. There are no big surprises. Most timezones follow modern-day administrative boundaries, with the exceptions being Xinjiang, Xizang (Tibet), Qinghai, Gansu, Nei Mongol (Inner Mongolia) and Guangdong. There was an exception in Heliongjiang region on GMT+8.5 where the northern-most county Mohe is on GMT+8. A few other exceptions were two counties on the Sichuan side of the Xizang - Sichuan border, counties Dege and Baiyu which lies on the Sichuan side and are therefore supposed to be GMT+7, Xizang region being GMT+6, but Dege county is GMT+8 according to astro.com while Baiyu county is GMT+6 (could be true), for the moment I am assuming that those two counties are mistakes in the astro.com data. The biggest surprise was that region Guangdong were dived in 3 timezones, a south/west part on GMT+6 (counties Xuwen, Haikang, Suixi, Lianjiang, Zhanjiang, Wuchuan, Huazhou, Gaozhou, Maoming, Dianbai, Xinyi) a central part on GMT+7 (counties Yangchun, Yangjiang, Taishan, Kaiping, Xinxing, Luoding, Yu'nan, Yunfu, Taishan, Deqing and Enping) and a north/east part on GMT+8 with the rest of the counties. Zone Asia/Harbin on GMT+8.5: regions Heilongjiang (minus Mohe) and Jilin. Zone Asia/Shanghai on GMT+8: regions east Nei Mongol, Liaoning, Hebei + Beijing, Shanxi, Shandong, Henan, Jiangsu, Anhui, Shanghai, Zhejiang, Hubei, Hunan, Jiangxi, Fujian, north/east Guangdong and Mohe county of Heilongjiang. Zone Asia/Chongqing on GMT+7: regions west Nei Mongol, Ningxia, Shaanxi, east Gansu, west Qinghai, Sichuan, Guizhou, Guangxi, Yunnan, Hainan island and the central part of Guangdong province. Zone Asia/Urumqi on GMT+6: regions east Xinjiang, west Gansu (counties Dunhuang, Aksay, Anxi, Subei), west Qinghai, east Xizang (Tibet) and east Guangdong. Zone Asia/Kashgar on GMT+5: regions west Xinjiang, west Xizang.

More daylight savings in Australia
by Eric Ulevik July 23, 2007

July 23, 2007

The states of NSW, Victoria, ACT, Tasmania plan to harmonize DST, starting October 2007. "Under the plan, clocks will go forward one hour on the first Sunday in October, instead of on the last Sunday, and will be wound back by an hour on the first Sunday in April, rather than on the last Sunday in March." http://www.news.com.au/story/0,23599,21549128-2,00.html Regards, Eric Ulevik

proposed change to 'zic' to support "outlandish" offsets
by Paul Eggert May 4, 2007

May 4, 2007

Currently zic allows only GMT offsets in the range -24:00 to 24:00. And yet the recent query about Mt. Athos led me to think that in some cases it can be useful to allow GMT offsets outside the range, to approximate the Julian calendar. And at any rate zic should be able to generate whatever offset can be stored in the standard tz file format, if only for testing purposes. So here is a proposed patch to the zic code and documentation to support this. I'll follow up with a message illustrating how this might be used to support Julian dates and civil times on Mt. Athos. =================================================================== RCS file: RCS/zic.8,v retrieving revision 2007.4 retrieving revision 2007.4.0.1 diff -pu -r2007.4 -r2007.4.0.1 --- zic.8 2007/03/20 12:48:10 2007.4 +++ zic.8 2007/04/23 22:27:49 2007.4.0.1 @@ -239,14 +239,35 @@ wall clock time is assumed. .B SAVE Gives the amount of time to be added to local standard time when the rule is in effect. -This field has the same format as the +This field's format is similar to that of the .B AT -field -(although, of course, the -.B w +field, except that the +.BR s , +.BR u , and -.B s -suffixes are not used). +.B w +suffixes are not used. +.IP +Also, for completeness, the +.B SAVE +field can be preceded by an +optional day count of the form +.IB N d +where +.I N +is a nonnegative integer number of days. +Both the day count and the time can be preceded by an optional sign; +if the second sign is omitted it is assumed to be the same as the first. +A day consists of 24 hours. +For example, +.B \-2d+23:45 +means minus 2 days, plus 23 hours and 45 minutes, and is equivalent +to +.B \-1d0:15 +which means minus 1 day, minus another 15 minutes. +The day count is not needed for any real-world example using the +Gregorian calendar, but it may be useful for testing, or for +half-baked approximations to other calendars. .TP .B LETTER/S Gives the @@ -287,15 +308,16 @@ zone. .B GMTOFF The amount of time to add to UTC to get standard time in this zone.

Turks & Caicos switched to U.S. DST dates?
by Paul Eggert April 28, 2007

April 28, 2007

On 2007-03-15 Chris Dunn reported to the Debian bug list that the Turks & Caicos Islands (America/Grand_Turk) changed their DST transition dates this year to match the U.S. dates; see Debian bug 415007 <http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=415007>. He made no mention of the time, so I guess we should continue to assume transitions at 00:00 local time. It'd be nice if someone could confirm this with a more-authoritative source.

2007 Year DST rules for Turkey

Recently I had informed you about the change in DST rules for Turkey, and you had provided the Time Tables with the modified rules accordingly. Thanks for the same. I came to know that Turkey has changed again the time at which the DST starts and ends this year 2007 at a very late stage. The DST now starts at 3:00AM on 25th March 2007 and ends at 04:00AM on 28th October 2007 as against 1:00AM on 25th March 2007 and 2:00AM on 28th October 2007 respectively (as per the previous rules). The latest rules are available at - http://www.timeanddate.com/worldclock/timezone.html?n=107 I have some official information as well on this at the following websites: 1. http://www.ntvmsnbc.com/news/402029.asp 2. The following link is the Turkish Official Newspaper's page: http://rega.basbakanlik.gov.tr/ Since there was no direct link to DST rules announcement, a Turkish person has provided the below attached document to show you how you can get access to the formal DST announcement in the above link.

Question on interpretation of rules intervals
by Liviu Nicoara April 13, 2007

April 13, 2007

Hi all, I have a question about how to interpret the US set of rules. After going through the "zic" man page and the mailing list archive I am still unclear about the meaning of using this: [...] Rule US 1942 only - Feb 9 2:00 1:00 W # War Rule US 1945 only - Aug 14 23:00u 1:00 P # Peace Rule US 1945 only - Sep 30 2:00 0 S [...] in a zone definition like this: Zone America/New_York -4:56:02 - LMT 1883 Nov 18 12:03:58 -5:00 US E%sT 1920 -5:00 NYC E%sT 1942 -5:00 US E%sT 1946 [...] As I see it, the US rule has a transition in 1942 (only), on Feb 9th, where it saved 1 hour. Am I correct in interpreting the gap of 43-44 as: 1. The transition of 1942 was observed up until 1945, Sep 30th, and... 2. The entry for Aug 14th, 1945 transition exists only in order to be used in time zones which did not observe the 1942 transition? Thanks, Liviu

Tomorrow's _Daily Star_ reports on its front page that the government of Bangladesh is likely to observe daylight saving time to manage a power crisis. It does not give details about when it would be observed, but it sounds like it'd start later this month.

Iraq sprang forward twice this weekend
by Paul Eggert April 2, 2007

April 2, 2007

The AP reported today that the Iraqi government issued a statement two weeks ago saying DST would begin yesterday (March 31) at 00:00 local time. At the appointed time the American military obediently shifted its clocks forward, but state-run TV did not. Apparently the cabinet had changed its mind, without notifying the Americans. State-run TV later announced that the government had decided to change the time today at 00:00 local time instead. No changes are needed to the tz database for this one, since it agrees with what the Iraqis eventually ended up with. We were lucky that we didn't get that statement two weeks ago. Here's a reference: http://www.latimes.com/news/printedition/asection/la-fg-time1apr01,1,460739…
