Do you keep your bios/cmos clock set to local time? The installer
creates a file /etc/wall_cmos_clock as a flag if you set it up this way.

The normal setup is to keep the bios clock on UTC, and then FreeBSD
works out the local time - including DST. But if you run on local time
I don't think FreeBSD handles DST in the cmos clock because that mode
is intended for dual-booting.
