dmesg: Invalid time in clock: check and reset the date

[Richard Smith]

Hi, I've just installed FreeBSD 7.0 Release along with Windows XP on my PC. I found that when I set the clock to the correct time&date, next time I boot into FreeBSD it changes and reports the wrong time&date. Both BIOS and Windows reports the time correctly.

dmesg shows the following message:
Invalid time in clock: check and reset the date!

Can't figure out what's wrong... any help will be appreciated.

regards
