Merhaba Serkan, Turkey is constantly one hour ahead of most of Europe, but the DST switch occurs simultaneously in Turkey and Europe. The rules in the Time Zone Database are correct. This page illustrates the upcoming DST switch: http://time.is/compare/0000_31_Mar_2013_UTC/CET/Turkey Sincerely, Even Scharning Time.is - exact time for any place on earth http://time.is/ On 2013-03-25 7:18, Serkan Kaba wrote:

Hi,

The time at night where Turkey switches to DST is different from rest of the Europe. Please check http://www.timeanddate.com/worldclock/clockchange.html?n=19&year=2013 for details.

Regards, Serkan

It should have been different local time. Anyway now resolved. Thanks for your interest. ________________________________ From: Andreas Schwab <schwab@linux-m68k.org> To: Serkan Kaba <serkan_kaba@yahoo.com> Cc: "tz@iana.org" <tz@iana.org> Sent: Monday, March 25, 2013 8:15 AM Subject: Re: [tz] Turkey DST time Serkan Kaba <serkan_kaba@yahoo.com> writes:

AFAICS, all of Europe switches at 01:00 UTC, including Turkey. Andreas. -- Andreas Schwab, schwab@linux-m68k.org GPG Key fingerprint = 58CA 54C7 6D53 942B 1756  01D3 44D5 214B 8276 4ED5 "And now for something completely different."
