Yes, some alarm clocks do count the cycles "from the wall".

Source: I helped a friend hack his clock to change his alarm clock from 60Hz to 50Hz.

I'm fairly curious about how you did that, and if the same is doable for larger load devices (60Hz -> 50Hz or 50Hz -> 60Hz).

It's not difficult, the IC has a pin to select between 50Hz and 60Hz so you just need to solder one or two resistors to make it work.
