Perhaps even a bit easier:
paqi% dumpfs /dev/ad0s2a | head -1
magic 19540119 (UFS2) time Sun Mar 18 15:48:35 2007
Also, 'dumpfs <device> | head -20' provides far more than anyone wants
to know but including maxfilesize, flags (eg none or soft-updates) and
fsmnt (last mounted on). Works on unmounted or mounted drives.
