When I built mine, my goal was to be able to rebuild the same thing I tested later on a different machine, so I used a specific date in my supfile: *default date=2011.09.27.00.00.00 But you can also do: # uname -a FreeBSD bcnas1.bc.local 8.2-STABLE FreeBSD 8.2-STABLE #0: Thu Sep 29 15:06:03 CEST 2011 root@bcnas1.bc.local:/usr/obj/usr/src/sys/GENERIC amd64 Which as you can see, tells you a time somewhere around the csup'd version (Sept 27), but it is actually the build time (probably 'make buildkernel'). I am not sure what it would say for something you get from an iso (would it be a week after the release tag the day it was built, or the tag date, etc.). But if you install a snapshot, such as the 8.2-STABLE-201105 iso you can find on ftp, it says 8.2-STABLE-201105 instead of 8.2-STABLE.
