On the Model 100, the time is store at RAM address 63795 and occupies 6
bytes for the time ... one byte per digit of time:
63795: SEC, 1's
63796: SEC, 10's
63797: MIN, 1's
63798: MIN, 10's
63799: HR, 1's
63800: HR, 10's

Well, he wants to subtract one time value from another. Presumably
we'd want to serialize both times, store them in a double, dblTime =
(if HH=0 then HH=24) HH*3600+MM*60,+SS, do the subtraction, then build
another time string to display. Lots of expensive string ops,
VAL()s... surely peeks would be quicker, if messier, though I suppose
the different models might put the time in different memory locations...

The other question is if 1 second is fine enough resolution.
Presumably it is if string time is adequate.
And yes, the current clock values are maintained in RAM
somewhere. The question becomes the time for a single string
= operation vs. multiple RAM address reads from BASIC.

Clarify some things please:
What is the max interval?
Is the max interval longer than 24 hours? If so, we need date
also.
Do you want shortest, or fastest, or best compromise?
Questions for the more experienced among us:
Is there some memory location where the system time is
available as a number? If so, we would prefer that. Even a
tick count would be handy.

I suppose I could lamely offer this as a challenge, but
the fact is that I am just lazy, and am wondering how
others would go about it.
The issue is the shortest code that will collect (as a
character string, H:M:S) the difference between two clock
readings, in hours, minutes and seconds. The crux of the
matter is the capture of interval between randomly
occurring events.
Assume
A$=TIME$ 'First event
B$=TIME$ 'Second event
