delay between commit and repository acknowledgement

We are trying to understand a delay between commit and acknowledgment by the
repository. Here is an excerpt from a user's log. The last entry is the one
that's interesting. Note the time and date:

Here is the excerpt for the same revision span (277 thru 284) from the
repository. Note the time of the last entry:

So, Geoff committed to make revision 277 on Monday, August 14, 2006 1:57:27
PM, and the repository reports this as 2006-08-14 14:00:11 -0700, which
could just be a difference in their clocks; anyhow, it's nearly
instantaneous. But then he committed to make revision 284 on Monday, August
14, 2006 8:58:51 PM, and the repository reports this as 2006-08-15 08:39:41
-0700, which is nearly 12 hours later.

My question is: what causes this delay?

Is it that the repository doesn't update its log until someone actually asks
for an update (i.e. more than status -u, all the way to update)? I propose
that solution because we know that someone did do an update at about that
time (8:39 the next morning). If so, is that a bug?

PS Another datum, possibly irrelevant: the commit to make rev 284 lacked a
commit message.
