As has been mentioned repeatedly in this thread, the short-term accuracy
of power-system frequencies is several (many?) orders of magnitude worse
than your stated requirement (they 'run slow' at times of high demand,
but are carefully made to 'catch up' at other times so that domestic
clocks, etc., don't develop cumulative gross errors).
That's why that won't work...
Your confidence that the videogame's(!) registers 'will have undergone
1,296,000 increments over the course of 6 hours' is certain to be
similarly misplaced, though if crystal-controlled perhaps only to the
extent of a few hundred increments.
I'm well aware of the drift.
This, basically, is IMO why no-one can see the point of your
accuracy-requirement - you seem to believe that you need it to 'keep in
step' with a process that is proceeding at rate only approximately-known
but from which you can't derive any synchronising-information.
No. It is only approximately known, but the "synchronising-information"
will be *visually* assessible from the monitor screen.
