It would seem so or it was too late to be reading it :)

Mine doesn't look like yours :) see below.

No, I am just fanatical about the time I send messages and it would seem
to be the one part of my Linux system I 'can control' and know how it
works. :)

From the /var/log/ntp file I have extracted the below snapshot:

2 Nov 15:32:20 ntpd[4652]: synchronized to LOCAL(0), stratum 10
2 Nov 15:32:20 ntpd[4652]: kernel time sync disabled 0041
2 Nov 15:33:25 ntpd[4652]: synchronized to 202.135.38.18, stratum 2
2 Nov 15:33:25 ntpd[4652]: kernel time sync enabled 0001

Besides the 'kernel time sync disabled/enabled messages, to me it looks
like the clock is being synced. Would I be right?
