The Doppler has the ability to display the time offset slightly for those that want. There are many reasons for applying a Time Offset to your Doppler, for example maybe you want the Doppler to display the time 5 minutes ahead of the actual time so you will be a little bit early to work. 

To set a time offset just go to clock setup mode and change the time to whatever offset you'd like: 

Hold until colon blinks, press or hold or and to save.

The return to the correct time and delete the offset (assuming you're connected to the internet):  Hold until colon blinks. Press to reset and  to save.
