Need to trim space from time field

I've got a text box in my report where I am dropping in two times: start time and end time.

{EarlyShiftStart}-{LateShiftEnd}

My problem is if the late shift end is a time less than 10, it adds an extra space between the "-" and the start time.

So instead of:

8:00 AM-3:00PM

it is 8:00 AM- 3:00 PM.

Is there a way to have this extra or padded space removed?

Thanks,
