If you turn on ntpd's rawstats, it will write an entry for each packet 
exchange with 4 time stamps.  If you assume the clocks on both systems are 
accurate, you can get the transit times in each direction.  That will tell 
you which direction is having troubles.  That may or may not be useful 
information.

You can make ntpd poll more frequently with maxpoll on the server line.  I 
think the normal default min is 64 seconds.  You can get more by using more 
servers.  If that's not fast enough, poke me off list and I'll write a hack 
that will do it faster and/or write the log files in a format you like.
