Not enough information about what you're trying to do: Are these
synchronized against an outside source of time? Are you using a local
source of time such as a GPS receiver? Or are your servers sitting
there with nothing but the undisciplined local clock and something like:
server 127.127.1.0 # local clock
fudge 127.127.1.0 stratum 0
in the config file?
What's
ntpq -c peers
showing?
As a general sort of rule, if you're synchronized to some trusted time
from somewhere, your stratum is going to be one higher than the stratum
of the server you're synchronized against, and you rather have to go out
of your way to override that.
