time.nist.gov is of course a stratum 1 server, and if the other 2 are 
synced to it, they are stratum 2 servers.  It is customary to _not_ sync
from a stratum 1 server unless a large number of other machines are syncing
from you, and then to get permission.  It is also generally polite to get
permission / inform stratum 2 servers if you plan to use them.
 
Also, if you are just using ntpdate to sync, and not xntpd, using a stratum
1 server is kinda silly.  Find a few nice stratum 2 and 3 servers and sync
from them.

A nice list can be found at ftp.udel.edu somewhere in /pub/ntp -- it might
be in the xntpd distribution itself.  Lots of nice stratum 2 servers to
sync to.
