So, what degree of accuracy are you really needing?
1/60th of a second...
(ie: When the 2 hour, 53 minute, and 37 second point is reached, the
display should show it at exactly that time at an accuracy of 1/60th of
a second from when the clock started running).

You have no idea what your requirements mean. A drift of 1ppm in 6 hrs is
meaningless in a marathon or other race, when the wind can easily cause
1% change in performance.
So in Brooklanese -Fahgettaboutit!
There is no wind involved here.
I've been trying not to get into the details, because details lead to
the request for more details, and this is just way to complex to get
into here. Not just as far as what I'm doing, but the timer I am
seeking is actually inadequate for all of the experiments I want to do.
Now if this is so difficult to understand, then the more complex timer
will be near impossible to explain.
For this project there will be 1,296,000 increments over the course of
6 hours. I just need the option of *visually* seeing on the timer's
display when each second increments beginning with the press of a start
button, and the accuracy must be 1/60th of a second at worst for any of
those 21,600 seconds after zero.(I'm assuming that the timer will have
to be plugged in an AC outlet).
