>From my logs I can see that my system clock is consistently drifting
about 3 seconds every 24hrs and ntp is faithfully correcting it. Can
the kernel track long term data like this and insert/remove a few
extra ticks to minimize the size of the ntp drift corrections?

ntp should do that anyway - check you have a drift file defined in ntp.conf
# Drift file. Put this in a directory which the daemon can write to.
# No symbolic links allowed, either, since the daemon updates the file
# by creating a temporary in the same directory and then rename()'ing
# it to the file.
#
driftfile /etc/ntp/drift
Over time it will adjust to suit and step the changes gracefully.
