Hi, I recently upgraded to TFS 2013 U2.
Since this update, some of our scheduled build began running 1 hour earlier.
For example, a build scheduled at a specific hour (19:00) is triggered 1 hour earlier (18:00).
All the computer (TFS server, SGBD server, build server, TFS client) have the same time and timezone, the good one, so we don't understand this behaviour.
I always submitted the question (http://social.msdn.microsoft.com/Forums/vstudio/en-US/f8b4ca42-c3c7-4cd3-9d26-84de15429629/scheduled-build-launched-1-hour-earlier?forum=tfsbuild) but up to now no effective solution.
