TEst 1 and 2 test to make sure that the timestamps make sense (eg are not the
wsame as an old packet and pairs with the last one sent to that peer) test3 is
that the originate and receive timestamps are non-zero, Test 4 is taht the
delay (round trip time) be reasonable, abc are subsets of that, 5 is
authentication, test 6 irequires peer clock by synchronized and that the
itnerval since the peer clock was last updated is positive and less than
NTP.MAXAGE, test 7 that the host has no lower stratum than the server, and 8
that the header contains reasonable values for rootdelay and rootdispersion.

Ie, if any of the tests are out the server's time is too suspect to use. Your
server is problematic.

It means that the round trip time is out of spec. And it looks like your
source, whatever that is, went nuts and jumped by 2 sec suddenly. that is why
you should be using at least 3 sources. If one goes mad, the others can
outvote it. If you only use 1, then its time is by definition right, even if
it is out by 40 years.

Talk to the person who is sysadmin on the server and find out what happened. 
Use more than one server.
