If you reserved a register for "Last Correction Time" (Say R99) then whenever you run your program
it could use the difference between R99 and current time and compute the correction factor, then it
could update the current time and save the current time into R99 for the next calibration.

This way your calculator's time gets corrected whenever you run the update program, but consumes
only the normal idle/off power in the mean time.

To be even more useful, this could be included in the firmware and the correction could be automatically performed (if necessary) whenever the date or time is queried.
