The time zone rules for Istanbul, Turkey have not been changed for years now. It seems like that it was last updated in year 1985 or so.
The latest rules are available at - http://www.timeanddate.com/worldclock/timezone.html?n=107
Thanks for the info. For our reference, can you please point us to a more-official web site that contains this information? Preferably English, but it's OK if it's Turkish. The Turkish goverment would be best, but newspapers are fine. Also, can you please try the following patch yourself, and verify that it's right? This patch changes time stamps only for 1991 and later. I could not find any discrepancies before 1991 between the current tz data and the source you cite. 1991 != 1985, so I'm worried that I've made a mistake in it.
