iCal month view - appointments over two days

Very annoying but when entering a new event in the month view it defaults to an all day event - ok I can cope with that.

But when double clicking the new event to change it to a timed event (still in month view) and tabbing through the dates and time, the duration seems to default to 6+ hours, so after 17:00 defaults to being over two days and it is too easy to miss changing the end date.

Is there a way out of this?
