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:
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
