Quicklaunch Start times

When creating Quicklaunch start times, it doesnt let you choose a time that exists before the current local time, however with people in different timezones, this may be wanted. E.G. In australia I just chose the quickest start time for the launch, (5 mins away), and it put the launch time not in as local time (the time used to test form submission) but as UTC, the time used to start. So now the launch doesnt start for ages even though I couldnt choose an earlier time.
