Hi,
I'm in the middle of migrating our oracle servers to RHEL and C6; while testing ntpd I'm seeing time resets.
I see in sysconfig/ntpd the option g is set which means huge offset is one time ignored. But my understanding of ntpd is, it slows or accelerated kernel clock but does not make huge jumps...
Is this really expected behaviour?
The file step-tickers is empty, ntp.conf is minimal:
driftfile /var/lib/ntp/drift restrict default kod nomodify notrap nopeer noquery restrict -6 default kod nomodify notrap nopeer noquery restrict 127.0.0.1 restrict -6 ::1 server 10.0.1.27
