We are losing about 15 seconds per 86400 seconds = 0.0001736. I
suppose that is the error we can expect based on the crystal they are
using and the algorithm to give the system 100 tics per second. My
preference would be to figure out how to patch the kernal to correctly
compensate the system time so that it is the same acuracy as the
crystal, hopefully less than 1 second per day error. Individual
programmers should not have to write non-portable code to keep the
system time correct.
