As someone who does do Y2K tests (albeit not on FreeBSD) I'm qualified
to grab this one. It's done in single user mode, just before the
machine reboots. Typically, you've got so many other services running
that might be time sensitive (cron/at are the obvious ones, but anything
that does logging is a candidate, databases, and so on).
On Solaris, this is accomplished with a trivial shell script linked in
to /etc/rc0.d/K999newdate, which just reads in /new-date, and sets the
date and time appropriately.
# echo 123123501999 > /new-date
# init 6
works quite nicely.
The sound as 30 E450s, fully laden with disks, shut down almost
simultaneously is really quite disturbing if you've been conditioned
to *always* hear the noise of the fans in your machine rooms.
