Hi, According to the http://www.timeanddate.com/worldclock/city.html?n=107 Turkey is observing DST same as EU but instead of using 1:00 local time, they are using 1:00u. A closer look in the europe file, will show that they use EU rule with no change (1:00 local time). According to unofficial sources in Turkey, and Worldclock representant, the right value would be 1:00u. Please advice how to proceed to make the data into the next release of tzdata. Regards, Tiberiu Covaci

Sorry, I don't see why a change would be needed to the tz data. For example, here is the output of 'zdump -c 2006,2008 -v Asia/Istanbul'. The transitions are at 01:00 UTC, just as you wrote. Asia/Istanbul Sun Mar 26 00:59:59 2006 UTC = Sun Mar 26 02:59:59 2006 EET isdst=0 Asia/Istanbul Sun Mar 26 01:00:00 2006 UTC = Sun Mar 26 04:00:00 2006 EEST isdst=1 Asia/Istanbul Sun Oct 29 00:59:59 2006 UTC = Sun Oct 29 03:59:59 2006 EEST isdst=1 Asia/Istanbul Sun Oct 29 01:00:00 2006 UTC = Sun Oct 29 03:00:00 2006 EET isdst=0 Asia/Istanbul Sun Mar 25 00:59:59 2007 UTC = Sun Mar 25 02:59:59 2007 EET isdst=0 Asia/Istanbul Sun Mar 25 01:00:00 2007 UTC = Sun Mar 25 04:00:00 2007 EEST isdst=1 Asia/Istanbul Sun Oct 28 00:59:59 2007 UTC = Sun Oct 28 03:59:59 2007 EEST isdst=1 Asia/Istanbul Sun Oct 28 01:00:00 2007 UTC = Sun Oct 28 03:00:00 2007 EET isdst=0

The right time seems to be 1:00s (not u), so they are not on the EU rules, just almost. I have not yet had time to research when this started, but based on old news reports, it seems that has been so at least since 1997, two examples (1997 and 2006): http://www.byegm.gov.tr/YAYINLARIMIZ/CHR/ING97/03/97X03X25.TXT (search for summer time) http://www.hurriyet.com.tr/english/5305826.asp It is on my TODO-list to research this further, to correct old timestamps.
