Try the string "2008-04-11 00:02:00 +0200". Same timestamp. Different date.

The idea of an implicit timezone is nice in theory, but it comes with 
the responsibility of ensuring that the timezone is respected correctly 
everywhere a date is used. Practically, this just isn't going to happen, 
which means the bug will keep coming back.
