What does schedule duration actually do?

Hi,

I am trying to schedule a bar to stay on for 24 hours 2 days a week (24 hours Thursday & 24 hours Friday) .

I have it set to recurring schedule
Weekly
Days Ticked Thurs & Fri
Hour 0 Min 0
Schedule duration 1440

The start date is set for tomorrow and the end dat is set for a few weeks time.

For some reason though it still says:
Current Start Time: Thu, Jan 19, 12:00 am Current End Time: Fri, Jan 20, 12:00 am

What am I doing wrong please?
