What’s normal? The messages are in response to what the client ntpd detects
when comparing the local clock with the set of configured servers (peers).
IIRC:
no_sys_peer Indicates that there is no server that satisfies ntpd’s
stability criteria.
spike_detect This is informational in that a difference between the local
clock and the valid servers was temporarily greater than the 128ms max offset.
clock_step Normally modifies the local system clock frequency to adjust
for differences between it and the valid servers. If the offset is greater than
128ms, then unless
configured otherwise, will step the system clock.
