Incorrect kernel time on laptop boot

  Hi,
 
I currently experienced a problem with my Sony Vaio VGN-FE31B laptop.
Each time I boot, from my user point of view, the kernel time seems to be
set with the wrong date time.
I have poweroff the machine, wait for a whole day, and I reboot again, the
kernel time is set with yesterday's date and time.
It is like some clock has completely stopped on power off.

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.

Any ideas ?
If anybody can point me to the right kernel source file(s) so I can try
to figure out what has changed, it would be a good start for me ;)


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