Not to mention that grid frequency is nowhere near as stable in the
claimed tau as a 32.768kHz xtal...

Now, if they averaged for a month, then maybe...

And before anybody claims they do:  You do realize that mains may
have the same frequency, but not the same phase from one 3-phase
transformer to the next ?
