Wierd things with NTP



Anybody else notice some odd behaviors with xntp over the past
couple of days.  I had a plethora of servers doing this since
since Sept 8th.

Sep 10 10:53:00 hb-esd102 xntpd[1185]: time reset (step) 0.170047 s
Sep 10 10:57:35 hb-esd102 xntpd[1185]: time reset (step) -0.314797 s
Sep 10 11:02:36 hb-esd102 xntpd[1185]: time reset (step) 0.318127 s

As you can tell, the host is moving time up and down every 5 minutes.
Then all of a sudden this morning at 6am, every server stopped doing it.
The hosts get their time from a pair of xntp servers with locally
attached stratum-0 GPS antennas.

Anyone aware if the govt is smudging the time source to reduce 
GPS accuracy?
