8.6.3 Set time (BIOS)

     # date MMDDhhmmCCYY
     # hwclock --utc --systohc
     # hwclock --show

This will set system and hardware time to MM/DD hh:mm, CCYY. Times are displayed in local time but hardware time uses UTC.

If the hardware (BIOS) time is set to GMT, change the setting to UTC=yes in the /etc/default/rcS.
