Hi Jason. Have you performed the following actions?
Electronic Timing Center (Analog Clock w/Digital Display)
Synchronizing the analog and digital clocks
1. Press the "timer" and "start time" buttons simultaneously.
2. Turn the set knob to move the hands on the analog clock to any time setting.
3. After five seconds the display will go blank. Press the timer button and using the set knob, set the digital time to the exact time on the analog clock. This will synchronize the two clocks. You can now set the time of day.
Setting the Time-of-Day
The time-of-day must be set before any other program can be used. When your oven is first connected to the power in your home, the digital display will show 00:00. To program the time-of-day:
1. Push and hold the "timer" and "bake hours" button at the same time.
2. Turn the "Set" knob until correct time is displayed on the digital clock.
3. Release "timer" and "bake hours" button
The analog clock will automatically set after the digital time is set

Let me know so that I may follow up if need be.

For the 720ef , this is what you need to do. Hopefully this will translate to your 900.
There are five buttons on the clock panel and from left to right they are:- Minute Minder, Cook time, Ready Time, Plus and Minus.
TO SET THE TIME OF DAY
Press the Cook Time button and the Ready Time button simultaneously. Use the Plus and Minus buttons to set the time.(24hr clock).
TO SELECT AN ALARM TONE.
Press the Minus button to listen to the first tone. Release it and press it again to listen to the second tone etc (3 tones)
Releasing the button after the tone has sounded will automatically set that tone.
SETTING THE MINUTE MINDER.
Press the Minuter Minder button and either the Plus or Minus buttons simultaneously to set the time.
You can cancel the timer at any time by setting it back to 00.00 by using the Minus button.
After setting, the display will revert to the time of day, but by pressing the Minute Minder button again, the display will show the remaining time.
To reset the cook time, use the plus and minus buttons to set it to zero.
To cancel the automatic setting and return the oven to manual operation, press the COOK TIME and READY TIME buttons simultaneously.
