Unmodifiable timedate.
 
Hi: I speak about the date command. Maybe I use it to correct the time some minutes. But after reboot, the clock is as before. Only makingthe correction in the BIOS menu does. How cann that be?

After setting the system time with the "date" command, use hwclock to set the hardware clock from the system clock.

Code:
hwclock -w
See the hwclock man page for more.

There are other ways to do this, but this one has been the easiest for me to remember.
