Store timestamps in UTC.

For now we just hardcode that the local timezone of the site is UTC+2.
Good enough for now, but something that should be configurable.

Also split the date and time entries in the form again, the date refers
to the start date. If the end time is before the start time, we assume
it's the day after. Again, good enough for now.
