On the Pro-C controller, I assume you are talking about program start times, such as 7:00 AM, not zone run times, because the Pro-C has 4 different program start times. Set start time 1 for whatever time you wish, say 5:00 AM, and set the other start times to OFF. The display should not say 0:00, because if your clock is set up for military time, 0:00 means midnight, and the controller is confusing itself with three of the same start times. The display should actually read OFF, so arrow over until each start time, other than start time 1, reads OFF on the display.
