[Sergio]

Hi!!..
i would like to add one hour to a timestamp field. F.e., the field show 2008-08-21.08:21:30, and the user wants to see one hour more (2008-08-21.09:21:30), because he has a problem with it field in his database.  How i can add it???....over the report or in the FM Model..???
Thanks a lot!!!...

If you are using a SQL backend, use the dateadd function
