As to those of the physical time in Linux?

Synchronized the system time and hardware:
hwclock --set --date='mm/dd/yyyy hh:mm:ss'
hwclock -systohc
Everything works, but if you set the time hwclock --set --date='mm/dd/yyyy hh:mm:ss', after the synchronization, sets the time after a system reboot.

Synchronized the system time and hardware:
hwclock --set --date='mm/dd/yyyy hh:mm:ss'
hwclock -systohc

The second command sinhroniziruete the hardware clock with the system time. First-just sets the hardware clock to a specified time without changing system time.

if you set the time hwclock --set --date='mm/dd/yyyy hh:mm:ss', after the synchronization, sets the time after a system reboot.

It is unclear what you want to say. Try to reformulate.
