I checked my watch just now, because the alarm was going off. I had Alarm 1 set to 9:30am, and the rest are set to 12:00am (default, haven't used them yet). So, I had Alarm 1 set to 'on,' and the rest of them off.... and the alarm still went off at 12:00 midnight - even though none of those alarms set for 12am were set to 'on!'
This is really weird, because the alarm only went off for 5 or 10 seconds - and it coincided with the atomic reception start time - but I don't remember it ever doing this before when it started syncing. Plus, I have it on mute, so it shouldn't be making that kind of noise in the first place unless I specifically had an alarm set.
Any ideas? Or is is just some function I don't know about that makes it beep when the atomic reception starts?
I have a feeling this may be related to the 'master alarm' bug, in that Alarm #1 may be turning the other ones on too, without the user telling it to, in the same way that it deactivates them when you turn #1 off.
