For a test if you have easy access to the microwave plug just unplug it for a few seconds and plug it back in and see if it is blinking. Kind of like my Keurig brewer. I can unplug it (the clock goes off) and plug it in and it retains time and memory either because it has a backup battery in it or just a slow discharging capacitor in the clock's voltage line.

Yes Ed, I tried that, but even just one second unplugged the microwave's clock reset to 00:00.
