A haunted clock

One of the local digital clocks has developed some odd behavior.

It's in a location where it doesn't get seen that much, so it never got reset to daylight savings time, and consequently has been off by an hour since the last time switch. But that's not the odd part.

The odd part is that some time in the evening, between 10 and 11 pm, it stops displaying 9:something or 10:something like it had been, and switches to 12:44. It will then stay on 12:44 for hours, usually all night and occasionally into the morning, before switching back to one-hour-before-current-time some time in the mid-morning. Then it stays at the (one hour off from) correct time all day -- it doesn't fail again in the afternoon to show 12:44 pm. It only does its 12:44 trick late at night.

Once I noticed it, I tried resetting it to daylight savings time, to see if that would kick it out of its old habits. After the reset, the time stayed correct through most of the evening (I had an insomniac night, so I had all too many chances to check it). But then in the morning, around 8 am, there it was, showing 12:44 again. It corrected itself before 10 am.

Definitely one of the odder failure modes I've seen in a while ...
