This fixes a crash when an event on the pc ends at midnight. In this case a record on the handheld is created which also ends at 00:00 but on the same date as it starts in stead of the next day.

I don't close the bug yet because the behavior of pc events running from day 1 10:00pm to day 2 9:00 am is not fixed by this commit. (Although I wonder if we will be able to actually fix this.)
