equivalent to "date -a"

[perryh at pluto.rain.com]

Does FreeBSD have an equivalent to the Solaris "date -a" command,
i.e. a command-level interface to adjtime(2)?  I didn't see any
mention of a "-a" switch in the manpages for date(1) or gdate(1),
nor anything applicable in apropos, and a grep for adjtime in
likely-seeming parts of /usr/src didn't turn up anything either.
