[SOLVED] Wrong hardware clock time

I just installed Mageia 1 32-bit release on my netbook. Followed these steps:
1- Before installation, I checked BIOS clock time, it was fine: 8:00 AM (timezone Europe/Madrid).
2- At Mageia installation, selected Madrid timezone (UTC +2)
3- After installing, and before first Mageia boot, checked again, everything fine.
4- Finally, after system boot, system clock marks 2 plus hours: 10:00 AM !!
Obviously, when I set system time to 8:00 AM, every time I reboot the computer the BIOS clock gets 6:00 AM. No dual boot or windows partition, only Mageia in the whole disk.
I have no idea why is this happening, any ideas?
Thanks in advance.
