Why? All that is needed is to increment a counter at every interrupt,
The Thundeerclock Plus manual has an interrupt handler, that handler could increment a counter and the clock() function simply reads the value of the counter.

Unless I'm missing something. If I am please tell me what it is.

I just checked AE Time II docs. That card has interrupts (both IRQ and NMI) at 1024 HZ and 1 HZ.
