Re: Timestamp problems

The problem is that hibernate does this mapping.
I have the Data stored as date and wan't to get the Calendar type, this one will
mapped to timestamp. But anyway, why is the timestamp manipulated.
Didn't i understand it right that the timezone offset to gmt has to be added at
the end, and here it should be +1 one and not +0
