“+” – Good and a preferred remote peer or server (included by the combine algorithm)
“*” – The remote peer or server presently used as the primary reference;
poll : NTP polls each peer every “poll” seconds.
when : is relative time of last poll.
reach : track of last successful polls, 377 is best.
Delay : is network delay, this is fine
offset : offset between local and peer clock (ms) and it should be low.
jitter : Mean deviation (jitter) in the time reported for that remote peer or server.
