Supposing I have a Stratum 1 time server and the time delivered by the
GPS receiver is wrong (without searching the cause for the moment). The
result may be like this:

ntpq> host xxxxxtime.xxxx.xx
current host set to xxxxxtime.xxxx.xx
ntpq> pe
     remote           refid      st t when poll reach   delay   offset
jitter

(captured Fri Aug  5 14:58:15 UTC 2005).

The server is in sync, reporting Stratum1, and the time is 2 seconds
away.

Are there any tricks to avoid this very unhappy problem ?

P.S. The example is from a real, well known Stratum 1 time server
(technically speaking, it's irrelevant to write the real name here).
