Description Sergey Pachkov 2011-10-07 08:35:07 UTC
in this year Russia changes rules for daylight switch

redhat/microsoft delivers an update for timezone rules and everything correct in OS except mono!

today Mono will return wrong local time (-1 hour). I have checked it with 2.6.7 and 2.10.2.

but when I set local time to 2012 year Mono returns correct time.

short solution is to set TZ=MSK-4 in environment before launch a Mono application.
Comment 1 Sergey Pachkov 2011-10-07 08:35:31 UTC
to get local time I use System.DateTime.Now
Comment 2 Sergey Pachkov 2011-10-07 08:54:21 UTC
after switch to Summer Time in 2011 year Russian break a switch to winter time and fixed timezone.
ex Moscow has +4 TZ

but mono/C# DateTime.Now returns +3 TZ (w/o difference of the year)
