You can try resetting your clock's settings every night and ensuring that you set the time one minute before midnight. This should prevent the buzzer from going off at midnight. If that doesn't work, try unplugging it for a few seconds and then plugging it back in to reset the clock. You could also try using a dedicated outlet for your clock, so nothing else is accidentally interfering with its timer setting. Finally, you could try replacing your current clock with a new one if none of these solutions work.

SPC900 manuals and others, but nothing for the SPC325.

You can get a manual at:

I don't know about your atomic sync problem. But here is how you can set the time zone:

Push the Time button once. This will change the Month/Day window to Alarm 1. Push the up button until the desired time zone is reached. Push the Time button twice more to return back to Month/Day display.

You must have more than one alarm setting and the second alarm is set for midnight. Turn the second one off.

I have a sharp atomic clock that once set for the exact time, after a day loses 3 hours.
