Maybe I've missed something in this thread, but if they're trying to add
a server to the pool shouldn't they be obtaining time from outside the pool?
I picked my parent servers off the lists from the ntp.org website, at
http://support.ntp.org/bin/view/Servers/WebHome It took a few days of
experimentation to find the most reliable ones with low round-trip
times, a process I've repeated whenever I've changed internet service
providers, but outside of such changes it's generally "set it and forget
it". Just monitor them periodically after the initial setup to make
sure they're still answering queries and you should be good to go.
One of the these days I'd like to get the hardware to run my own Stratum
1 server, which would make the whole finding peers process moot. :)

Hi Mingda Wang,
I saw one of your peers is located in the Netherlands, Europe. That explains the
round-trip times. Having stratum 1 peers is nice, but nearby stratum 2 or even a
few stratum 3 servers might be a better choice (if I remember right, the pool
monitoring system accepts up to stratum 5 servers in the pool). One way to
obtain
them is via 'host 0.asia.pool.ntp.org' (and '1...', '2...', '3...') multiple
times
at different times (to allow for DNS-rotation). Then check with 'ntpdate -qp 1
<<ip>>' the stratum and with traceroute (or traceroute6 for IPv6) the number of
hops. You can also check their scores and see if their score is stable.
