ntpd log question

I've started running ntpd on my notebook computer, and I've noticed the
following sort of entry occurs regularly in the log:

30 Dec 18:01:13 ntpd[681]: time reset 3.954465 s
30 Dec 18:01:13 ntpd[681]: synchronisation lost

Why does it say sync lost, immediately after reseting the time?

tnx jk

Hello James,

I notice the same in my own logs, such as during bootup:
Dec 30 17:14:05 green ntpd[824]: time reset -2.386063 s
Dec 30 17:14:05 green ntpd[824]: synchronisation lost
It seems to be normal behavior for a reset greater than 0.128 s, or, if I read
the below-mentioned newsgroup posting correctly, for when ntp is sync'ed to a
single server and the connection is lost.

Here's the posting:

It complains that it has been too far off the real time and there is a time
jump.

If the message comes after boot-up, add a call to ntpdate before starting up
the daemon.

Check that the computer is at least once sufficiently long (several hours,
preferably days) on-line with NTP to adjust the kernel PLL to the hardware
clock error. For details, see the NTP documentation at
<http://www.ntp.org/>.
