problem with new Date()

[melvintcs]

there is some error when i signing some event from code behind.

DateTime startTime = new DateTime(2012, 11, 10, 12, 0, 0); DateTime endTime = new DateTime(2012, 11, 10, 13, 0, 0);

the data above suppose to mark the event on 10 Nov 2012, but the calendar read as 11 Oct 2012.

But if i change the date to: DateTime startTime = new DateTime(2012, 11, 13, 12, 0, 0); DateTime endTime = new DateTime(2012, 11, 13 13, 0, 0); The system read it as 13 Nov 2012 which is correct.

please guide me how to make sure the system always follow the second standard? (yyyy, mm, dd)
