cute quote
by Steve Summit July 11, 2003

July 11, 2003

I came across this quote, and (call me a timezone nurd) the first thing I thought of was the tz database, so I thought I'd pass it along: Don't worry about the world coming to an end today. It's already tomorrow in Australia. --- Charles Schulz Have a nice day (or tomorrow, as the case may be)...

Karbala time in southern Iraq
by Paul Eggert June 23, 2003

June 23, 2003

On April 22 at about 0700 GMT the BBC News World Service reported that Shias in several southern Iraqi cities have changed their clocks to be "Karbala time". According to the story these Iraqis are 1 hour behind Baghdad, presumably because they are ignoring daylight-saving time. I heard the report on a radio station in Los Angeles, but haven't been able to find a copy at the BBC web site news.bbc.co.uk. Possibly the story was tape-delayed. This reminds me of the article in the Economist in June 2000, which said that Kurds were ignoring DST in northern Iraq. Rives McDow's excellent contacts at the time disagreed with this claim. Quite possibly a similar situation is occurring in southern Iraq right now.

Re: Canada's some little problems

> From: "Ciro Discepolo" <discepol(a)tin.it> > Date: Fri, 13 Jul 2001 14:50:36 +0200 > > I have noted some little problems respect DST in Canada analyzing > between Thomas Shanks data and the Time zone data I finally got around to decoding your attachment (sorry, I don't use Microsoft Word, so Word documents are a bit of a pain for me). Thanks very much for taking the time to correct the errors in the timezone tables; you must have gone to a lot of work! I have the following reaction to your comments: > Halifax does not use DST in the year 1932, while in the 1950 and > 1955 use a DST. Thanks for catching this error; I'll fix this in my next proposed patch. > From 1942 to 1944 Shanks says that ST JOHNS saved 1 hour (war time), > while in the timezone I've a normal DST from 1942 to 1944 without > stop. Here the timezone database was following Whitman rather than Shanks. However, Shanks seems more reliable about Canadian data than Whitman, so I'll change to Shanks here. > In the following table there are other date with difference from > Shanks, TIMEZONE and SHANKS contains the offset from GMT in DATE > TESTED. > > ZONE DATE TESTED TIMEZONE SHANKS > --------------------------------------------------------------------------- > GOOSE BAY 15-1-1943 3,3 2,3 > GOOSE BAY 15-1-1944 3,3 2,3 These discrepancies are for the same reason as St Johns, so changing St Johns will also remove these discrepancies. > GOOSE BAY 15-8-1917 2,3 3,3 > > NIPIGON 15-1-1941 5 4 > NIPIGON 15-1-1942 5 4 > > THUNDER BAY 15-1-1941 5 4 > THUNDER BAY 15-1-1942 5 4 > > RAINY RIV. 15-1-1941 6 5 > RAINY RIV. 15-1-1942 6 5 > > REGINA 15-8-1958 6 7 Thanks for catching these transcription errors; I'll fix them too. > MONTREAL 15-8-1917 5 4 But Montreal uses Canadian table #119, which says: 25 Mar 1917 2:00 4:00 24 Apr 1917 0:00 5:00 This means daylight saving time was not observed after April 24 of that year, so it seems to me that the SHANKS column should be "5". Perhaps the discrepancy is because you are using a different edition of Shanks? I am using the Revised 5th edition of Shanks's International Atlas <http://astrocom.com/books/full/b112x.php>. > WINNIPEG 15-1-1942 6 5 But Winnipeg uses Canadian table #171, which says: 26 Sep 1937 2:00 6:00 9 Feb 1942 2:00 5:00 so Shanks is saying that daylight saving time was not observed until February 9 of that year, so the SHANKS column should say "6". > EDMONTON 15/08/1918 6 7 But Edmonton uses Canadian table #179, which defers to table #5 for 1918, and table #5 says: 14 Apr 1918 2:00 6:00 31 Oct 1918 2:00 7:00 so the SHANKS column should say "6". > DAWSON FROM 1947 TO 1972 8 9 The timezone table says that Dawson was at 9 from 1947 to 1965; this agrees with Shanks, who uses Canadian time table #253. But that "1947 TO 1972" suggests to me that you've confused Dawson with Dawson Creek. Dawson Creek uses Canadian time table #251 and was at 8 (7 during summer) from 1947 to 1972. Thanks again for checking the database; your fixes should appear in the next version.

[(slightly) O/T] zic & leap seconds on Solaris 9
by Mariano Absatz May 12, 2003

May 12, 2003

Hi, I usually don't compile and install tzcode, and simply use the latest tzdata and compile the zones I need with the zic that my OS has... This has worked for linux and Solaris... or at least as far as I remember... now I wanted to use the "right" zones on a Solaris 9 machine and found that the zic that comes with Solaris doesn't support the "-L" option... So I downloaded & compiled tzcode (only adjusted the "cc = cc" line for using gcc). Everything went fine, I didn't install the software (it is in my home directory), but I ran: zic -d /usr/share/lib/zoneinfo/right -L leapseconds northamerica and it generated a new set of zone files in that directory. However, setting TZ to right/America/Mexico_City works exactly the same as if it were America/Mexico_City (i.e. I have _no_ 22 seconds difference). My (uninformed) guess is that maybe the old libraries cannot understand leap seconds although they are compiled in the zone files... I have a couple of questions: Am I completely off-base? :-) How could I replace the old version of the zoneinfo database, tools and libraries with a newer one? Browsing the Makefile, I see that the distribution of files is quite different from the one that appears to be standard in Solaris. Does anyone know of a ready-made Solaris 9 package I can use? I don't even know how to "uninstall" the default libraries or which files are involved... they don't appear to have the same names... This is a production machine and I wouldn't like to break it just to set the clock right :-) Any Solaris+Olson expertise would be greatly appreciated.
