c# - Wrong conversion of Moscow time to UTC -


the next code shows wrong local time if current location moscow:

datetime dt = new datetime(2010, 1, 1, 10, 0, 0, 0, datetimekind.utc); console.writeline(dt + " - " +  dt.tolocaltime());  dt = new datetime(2010, 7, 1, 10, 0, 0, 0, datetimekind.utc); console.writeline(dt + " - " + dt.tolocaltime());

output:

01.01.2010 10:00:00 - 01.01.2010 14:00:00 01.07.2010 10:00:00 - 01.07.2010 15:00:00

it should 13:00 , 14:00. how fix it?

p.s. os - windows 7 enterprise.

this bug introduced windows historical timezone data. there hotfix available (this applies windows 7, server 2008 r2 , others, not xp).

hotfix: update 2011 calendar history in windows operating systems

as jmk said in comments, may want consider excellent library nodatime instead, particularly if distributing program users may not have hotfix.
