If field05 doesn't contain the value 'gtz' the normal starting time is saved. e.g. Start date is "10.08.2007 10:00:00+02" the value is saved in this way in the database "2007-08-10 10:00:00+02". Otherwiese if field05 contains the value 'gtz' is only the date without time but with server offset saved. e.g. Start date is "10.08.2007" the value is saved in this way in the database "2007-08-10 00:00:00+02".
