Dear all,
Something I find myself getting confused by is the sign of Last Offset
and System Time. Does a positive difference in Last Offset mean the
local system is ahead of the remote, or behind the remote? Does a
positive difference in System Time mean the System Time is ahead of
the chrony estimate or behind? The docs are petty unclear on this
point.
Chrony and ntpd and RFC 5905 seem to differ on whether or not the
transmit timestamps come from the system clock or from the estimate
produced by ntp. Does this pose problems if there are a mix of
implementations?
Sincerely,
Watson Ladd
