rancid just uses CVS.  The only way it could have restored 2-yr old configs
would be if someone restored from tape, a very nasty log-filesystem bug, or
possibly (w/o having looked at the cvs source) an incorrect system clock
might do it.

It could also be that someone has purposely done it.  You can check for
other revisions (ie: newer than the one you're seeing) with cvs log; eg:

	cd /usr/local/rancid/groupfoo/configs
	cvs log | less

If the CVS revisions have multiple dots ('.') in them, you've ended-up with
a branch some how (again not something rancid does).  You can return to the
head with:

	cd /usr/local/rancid
	cvs update -AdP

To get configs from specific times/revs/etc, see the -p, -r, and -D options
of cvs checkout.  Also see the cvs FAQ noted in the rancid FAQ.
