run as root:
# date;hwclock
compare with date output
if not aligned – verify timezone settings
# hwclock –systohc
NOTE:
Before changing the hardware time, it is recommended that you run date to check whether the system time zone is the local time zone. Ensure that the system time zone is the local time zone. It means that you should use command “date” to confirm the OS time and time zone OK first . Then change the hardware time by the command above.
