Thank you for the pointed direction to these methods.This is possible.
To load a variable from a file on skin load, see:
https://docs.rainmeter.net/manual/skins/include-option/
To save the value of a variable to that file, see:
https://docs.rainmeter.net/manual/bangs/#WriteKeyValue
It worked like a charm with this.

Code:
[Variables]vStartingTime1=13364941886......LeftMouseUpAction=[!WriteKeyValue "Variables" "vStartingTime1" [mTimeNowCalc]] [!Refresh]
