Re: [tz] Tennessee time

The video from the Tennessee state house of representatives where this bill was pitched can be found here (about 10 min long): http://tnga.granicus.com/MediaPlayer.php?view_id=269&clip_id=8600&meta_id=15 8484 "... you came up with a Wang Dangger!" - Rep. Johnny Shaw I believe Rep. Todd is mistaken in his assertion that staying on DST year-round would give more daylight to schoolchildren waiting at the bus stop in the morning.

I think the fact that they could choose to call their resulting UTC-4 time zone "EDT" rather than "AST" probably wouldn't be in violation of the Uniform Time Act (but I'm not a lawyer either). That said, the federal Department of Transportation (which apparently has jurisdiction over such things) hasn't allowed Maine to move to Atlantic Time, so the odds that they'd allow Tennessee to do so seem rather low. (If Maine does ever manage to move its time zone, naming its zone identifier is going to be an interesting challenge for the TZDB -- since "America/Portland" is rather unfortunately ambiguous...) -- Jonathan Lennox lennox(a)cs.columbia.edu

timezone 2014 : Turkey delays DST start by one day
by Semih Sakiz Feb. 27, 2014

Feb. 27, 2014

Hello, According to Turkish government decision, there will be one-day delay in the start of DST. DST start time will be "2014 Monday, 31 March" instead of "2014 Sunday, 30 March" on Turkey. Is there a plan to update the time zone database for this change ? The latest timezone data on the URL "http://www.iana.org/time-zones" contains Time Zone Data v. 2013i and does not include the latest change in TURKEY. Here you can find the links for the change. http://www.timeanddate.com/news/time/turkey-starts-dst-2014.html https://bugzilla.redhat.com/show_bug.cgi?id=1065926 http://www.resmigazete.gov.tr/main.aspx?home=http://www.resmigazete.gov.tr/… [Description: Description: Poligon thy:2013:subat:mail imza:logo-tek-satir.png] Semih SAKIZ | Sistem Programcısı / System Programmer Türk Hava Yolları A.O.

The offical Chilean web site for time change now confirms that the time change will occur on April 26: http://www.horaoficial.cl/cambio_hora.html Thus, the current time zone files are accurate. -G.

Chile Time Change

Feb. 19, 2014

That much notice would be a blessing. In years before 2013, the changes were made with as little as 5 days notice (notice Monday for a change in the date scheduled for the following Saturday). And as I said before, we have a goverment change on March 11, so all bets are off. -G.
