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.
