Well, yes, I have dual boot with Windows, and I know it needs to have
BIOS clock set to local time. My FreeBSD is "tzsetup" to local time, no
UTC, and it has a /etc/wall_cmos_clock file and "adjkerntz -i" running.

At the time I wrote, my laptop still has its date and time set to
yesterday evening (local time), and it was powered off the whole day, today.

However, if I boot it with a FreeBSD 7.0-CURRENT-200610 kernel, its date
and time is set correctly. So, I might concluded that something has
changed between 200610 and 200611 snapshots.

Anyway, I don't know if it can help but here is a result from :
$ sysctl kern.timecounter
