The question:
I am trying to enter the value "30/03/2007 02:15:00" into a datetime column in MySQL and get the error "incorrect datetime".
What's wrong?

*update* Hint #1: format is okay, MySQL knows that 30 is day, 3 is month, 2 is hour and so on.
*update*: Solved! Answer here.

Fine print:
1. The free beer prize is available only within 25 miles of Ramat Gan. No beer-by-mail.
2. Shlomo may not participate.
