Day Pilot Scheduler(Asp.Net) - When does the day end (Event Resize)?

Scheduler - When does the day end?

Hi,

Im currently doing a trial of daypilot and it works almost perfectly.
However I have noticed some strange behaviour i would like to have explained so i can modify my code accordingly.
Take a look at your own demo: http://java.daypilot.org/demo/Scheduler/

Now lets first make a booking by drag'n drop using Event Resize (DayPilot Scheduler). Choose whatever resource and drag from september 3,2011 to september 6, 2011.
In the modal dialog the following dates will appear:
start: 2011-09-03T01:00:00
end: 2011-09-07T01:00:00

So it seems as the enddate is set to datetime 01:00 the day after september 6.
Now this is all fine as long as it is consistent.

Can you please explain whats going on here?

Thanks for your time!
