AFAIK, to keep good time on a linux machine inside the network, you need to run "ntpdate" and not "ntpd".
No no no! That just makes things worse! It's the most common reason for these "Time jumped forwards/backwards" warnings.
The machine runs FreeBSD not Linux :-)
So? The basic premise is still the same... the system clock should NEVER jump time like that during normal operations, if it does, something is seriously broken.
ntpdate, which causes large jumps, should only be used at boot time BEFORE server processes are started, then ntp CLIENT keeps the systems clock in sync using tiny increments, usually less than a second.
it runs ntpd pointing to several reliables NTP servers since 5 years
So something changed/broke? Happens all the time...
