Hmm, that might work. Thanks!
It should be surprising that your clock would jump by 6 seconds. Do
you have adequate upstream timesources (ie, at least 4) configured,
your local HW clock busted somehow, or are you doing something odd
with power-savings mode or running in a VM or something...?
One timesource, shared on local network, this machine is a client of
gateway, which uses only one source (ntp.alaska.edu, which is
10 minutes by car but thanks to Alaska bad peering, we go through
anyway). I checked the logs, that machine didn't step at all that
day (or any
other day, as far as my logs go). It always happens after reboot, as
indicated. No VM, no power-savings. The only odd things are
OK, a step upon boot is not unusual-- some machines have poor
timekeeping with the internal BIOS/battery-backed clock used when the
system is off.
Note that NTP falseticker detection really wants to have at least 4
timesources available for the algorithm it uses to detect whether an
NTP source is behaving poorly. Try contacting your ISP for nearby NTP
sources, or try adding 0.us.pool.ntp.org, 1.us..., & 2.us... to your
config; the NTP pool nameservers use a geolocation mechanism to some
extent to try and return NTP servers which are close.
