That last is the conclusion I'm coming to. I noticed earlier today that
my date was off by exactly one day (???), and ran '/etc/init.d/ntpdate',
which set it correctly. However, I've rebooted since then - and if you
take a look at the timestamp on my earlier email, it is again a day
early. I've just now re-run 'ntpdate', and it looks all right again:

``
ben at Fenrir:~$ date
Wed Dec 14 00:20:37 CST 2005
ben at Fenrir:~$ hwclock
Tue 13 Dec 2005 06:20:45 AM CST  -0.660403 seconds
ben at Fenrir:~$ hwclock --utc
Tue 13 Dec 2005 12:20:50 AM CST  -0.564115 seconds
ben at Fenrir:~$ cat /etc/adjtime
-11.214068 1055441761 0.000000
1134472469
LOCAL
''

Seems OK now - but I suspect that it'll magically go back to the wrong
time after the next reboot.

I do think, however, that the time being wrong is an *insane* reason for
'fsck' to report superblock problems. I still don't understand the mechanism
by which this is happening - or why it should happen at all.

I'm going to reboot this thing in the next few minutes and check the
time - presumably after dealing with the 'fsck' errors. :( Thanks for
the help, Kapil.
