In the switch, the hardware clock is separate from the software and is called the calendar.
This hardware clock runs continuously. After the hardware clock (the calendar) is set, the
FTOS automatically updates the software clock after system bootup. You cannot delete the
hardware clock (calendar).
To manually update the software with the hardware clock, use the clock read-
calendar command.
