Hi David
And have a problem with the "internal clock" because if i configure the date with "date 022101052005" (for example) after reboot one or two or three session i must configure new ...
It could be your /etc/adjtime Try setting the clock then deleting your /etc/adjtime file.BIOS clocks drift. This drift is calculated each time the clock is set and is stored in /etc/adjtime
On boot the BIOS clock time is adjusted by the value in /etc/adjtime and the system clock is then set to this adjusted value.
If you dual-boot OSX the clock should be set in UTC mode, iirc. - Mark
