These do seem to be larger values than you might expect from a clock
conditioned with ntpd. Is it a VM or is there something going on that
would stop or suspend your system?
There is certainly something wrong there.
System is not a VM; it runs 24/7 hosting for a few simple domains. It
runs OpenBSD, not Linux. I believe OpenBSD has it's own ntpd
implementation. I read once that the amount of time mentioned is how
much time clock needs to be changed, not how much the clock will
actually be changed. I know nothing about ntpd internals; thanks for
letting me hijack this thread. The log messages may be out-of-context,
since I excluded frequency changes. Still something wrong?
