jQuery with Date not working together with custom input format

I've turned on the "Date Popup" module to enable the jQuery date and time selection in Scheduler. In Scheduler, I've set the date/time format to:

n-j-Y G:i

with the "Date Popup" enabled, I get the appropriate jQuery calendar when entering the date. Underneath the time, the appropriate time format is displayed:

Format: 13:08

However, when I try to enter the time, the field is being displayed like this:

01:09PM

and if you arrow up or down through the hour, it goes 01 - 12 and then changes back to 01 with a change from AM to PM and vice versa.
