Time zone references in art
by Dave Cantor June 16, 2009

June 16, 2009

A possible addition to tz-art.htm : In the 1946 "A Matter of Life and Death", there is a reference to British Double Summer Time. The time does not play a large part in the plot; it's just a passing reference to the time when one of the characters was supposed to have died (but didn't). The IMDb page is at http://us.imdb.com/title/tt0038733/ Dave Cantor Groton, CT

tzdata2009i - Bangladesh
by Jesper Nørgaard June 15, 2009

June 15, 2009

Bangladesh is applying DST this 20.th.of June. In file tzdata2009i this is the attempt to implement it: Rule Bang 2009 only - Jan 1 0:00 0 - Rule Bang 2009 only - Jun 20 0:00 1:00 S Now that doesn't make sense to me at all. Bangladesh has not had anything close to "DST" since 1951, and then we zero-set DST January 1st. 2009? Then after implementation of DST next Saturday we leave it dangling for the next millenium? Probably this is really just a "typo" for Rule Bang 2010 only - Jan 1 0:00 0 - Rule Bang 2009 only - Jun 20 0:00 1:00 S So Bangladesh leaves DST with year end of 2009, since we have no authoritative information. But this is not a very good guess in my opinion, in fact Steffen Thorsen mentions semi-authoritative information: "On another note, Bangladesh's minister for power said earlier in 2009 that the new timing might continue until the end of September. Timeanddate.com will provide an update on the DST end date when it becomes available." Any guess in the end of September seems better to me, or October 1.st. 2009 at 0:00? ... perhaps this was why Dave Rolsky's test cases were blowing up? :) - Jesper Nørgaard Welen

tz file format

Hi, I hope i'm not wasting your time. I'm attempting to read the tz database into a c# application, and I'm not sure how to interpret this entry: Zone Australia/Hobart 9:49:16 - LMT 1895 Sep 10:00 - EST 1916 Oct 1 2:00 10:00 1:00 EST 1917 Feb 10:00 Aus EST 1967 10:00 AT EST What is the significance of the "1:00" on the row ending in "1917 Feb". Do I just add this to the 10:00 offset? Thanks, Russell

Understanding the Bangladesh change
by Dave Rolsky June 8, 2009

June 8, 2009

So I went to update my Perl package based on the Olson database this morning, and my tests are blowing up. The problem is that I don't have any code to handle the current Bangladesh situation. If I'm reading the database correctly, it says that there is a change scheduled for 2009, but then there's nothing scheduled for future years. Does that mean that 2010+ are considered unknown and uncalculatable? That seems somewhat problematic. I can't be the only one who expects to be able to use the Olson database to calculate future dates. -dave /*============================================================ http://VegGuide.org http://blog.urth.org Your guide to all that's veg House Absolute(ly Pointless) ============================================================*/
