I just moved the hands of my battery-operated clock forward for the time change and it doesn't work.

First replace the batteries with brand new fresh batteries. If that doesn’t work, you may have stripped the gears in the movement. Below are the proper ways to adjust the time on the battery-operated movements:

FOR CHIMING MOVEMENTS:

Set the time by using the hand set knob only.  DO NOT move the hands manually. Moving the hands manually can strip the gears resulting in the movement having to be replaced.

FOR NON-CHIMING MOVEMENTS:  

You can use the hand set or you can manually move the hour hand (shorter hand) forward in a clockwise direction.  DO NOT move the hour hand backwards (counter clockwise). Moving the hour hand backwards or moving the minute hand can strip the gears resulting in the movement having to be replaced.
