Why have you done this? First of all, leaf nodes should never have the local clock pseudo driver defined. Secondly, with modern versions of ntpd, the only real reason to use one on a non-leaf noed is if you are using a timing source outside of ntpd, in which case the local clock driver will be the only server defined.

When you want the whole network to coast together, you should use orphan mode.

If you must use the local clock as a fallback, I would advise defining enough real servers to safely outvote it, and setting the clock to within a second or so, before starting ntpd.

setting that flag , when I changed the date and trying to set it " ntpd -q
" command , when the first NTP packet is received, for the local address
hash iteration this condition[(!(peer->flags & FLAG_REFCLOCK] is failing
and returning as fit and trying to synchronize with local server and
printing the log "slew +0.0000000sec".. and all NTP packet exchange is
stopped after first pair exchange.

Yes, that's the sort of problem you get from inappropriate use of that driver.



If I remove this check [(!(peer->flags & FLAG_REFCLOCK] in peer_unfit
function, then everything is fine.Time has been reset to the server value.

It sounds to me that you have effectively removed the local clock entirely. The local clock needs to be treated as a refclock, so that time served remains valid indefinitely. On modern ntpd's, even without orphan mode or local clock drivers, a non-leaf node will continue to serve time long after its sources have gone away. However the root distance will increase until its clients decide it is too great.

I am not sure why this flag check is required?
