#45 SQL error when no startdate is given

[Matthijs Kooijman]

When adding a game, but not filling in any startdate, I get:
You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near ' 946767600, 1, 2, 'Aktiv')' at line 1

I presume this will be the same for not filling in an enddate.
