In fact using DateTime.Parse() is somewhat stupid ;-) Read here:
The DateTime.Parse method in the Microsoft .NET Framework
has goals much like its predecessors, but unfortunately it
suffers from some of the same problems. The code is slower
since the extra checking takes time, and there will always
be some new format that is not properly detected. In those
older products, you may remember, the behavior was sometimes
disparagingly referred to as "evil date parsing."
At least DateTime.Parse() is COM dependent where the behavior is
totally unpredictable and not countable from DateTimeFormatInfo.
