LINUX HACK 8

Hack 8.
Set Hardware Date and Time:
Before setting the hardware date and time, make sure the OS date and time is set appropriately as shown in the hack#7.
Set the hardware date and time based on the system date as shown below:
# hwclock –systohc
# hwclock --systohc –utc
Use hwclock without any parameter, to view the current hardware date and time:
# hwclock
Check the clock file to verify whether the system is set for UTC:
# cat /etc/sysconfig/clock
ZONE="America/Los_Angeles"
UTC=false
ARC=false
