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 set-system-date-and-time

 

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
