But isn't that what the drift file is for, to improve the accuracy of/usr/sbin/ntpd -c /etc/ntp.conf -p /var/run/ntpd.pid \It's generally recommended that you never trust your own clock since

it's completely crap as time sources go. It's also recommended that you
use at least 5 time sources to avoid problems with bad clocks.
the local clock during those times when the configured NTP servers aren't
available?
Yes, but it can only do so much. The clock crystals in your average PC are OK as clocks, but much better as thermometers so the drift calculations are only approximate.

Check your dmesg for NTPD log before you trust drift-files.
