Probably a faulty timer, but check to see if it has an automatic DST switch
that happened to trip if it is one hour even.

That timer uses a simple synchronous clock motor timer that depends on the
60Hz AC power for accuracy. If the clock motor runs at all it is probably
keeping time. There is no "DST switch". I suspect an operator error.

That makes sense, but for some reason the cheapos suck at keeping time.
I bought three of them on sale one day, and two of them were typically
off by an hour or so after a day or two.

The synchronous motor drives a set of fixed tooth gears which in turn drive
the time display. "Manufacturing tolerances" won't cause the timing
accuracy to change. The only probable cause for one of these timers to gain
or lose time is either a) operating a 50 Hz timer on a 60 Hz supply, or
vice-versa, or b) a power outage.

Sometimes the manufacturers screw up and put the wrong
timer motor into a piece of equipment. I have seen a 50hz
motor in a timer that was supposed to for 60hz. If you take
the timer out of it's case and look at the back you should
be able to see the motor which will have the voltage and
frequency printed on it.

I didn't stop initially to consider values, but (60/50)/(13/12) ~ 1.1
which is within 10% of the difference OP observed. Not an unlikely
hypothesis. Maybe he ordered the wrong subseries???

Actually, I'll agree on principle overall...was thinking of a short term
variability possibly, but on the long term, it has to run a revolution
per N cycles so not the OP's problem over 12 hours...

As noted elsewhere, the ratio of 60/50 to 13/12 is close enough to make
one wonder if OP order the wrong series number and got a 50Hz model or
perhaps it was just mislabeled...

I know that, but this one wasn't supposed to be running

Chuckle. A house my family had for a couple years back in the late 60s had a
built-into-the-paneled-wall kitchen clock like that. (Shaft stuck through
paneling, little brass squares that served as the numbers stuck to paneling
around it. Very Trendy for about a month in '66) Every time the power
blipped during a thunderstorm, it would start running backwards. Nobody ever
cared enough to pull it out from the access hatch in the pantry behind and
diagnose it. We just ignored it, or if company was coming, flipped the
breaker off and on.

Neither (a) or (b) would cause a synchronous motor timer to gain an
hour; (a) would cause it to gain 2.4 hours and (b) would cause it to
lose however many hours the power was off. If the gear tolerances were
off, however (tooth count or diameter off a smidge, it could well gain
an hour in twelve.
