Solved: I would guess that this is

Sunil Patil · ‎01-02-2015

Hi Team,

I am having 1 Cisco 5520 in our network. we don't have the NTP Server so we manually configured the Clock for the devices. We observed that when we give a soft (Command) reboot the box the time and day is updated. But we faced issue when we give a hand reboot (Power down by switch off the Power button) the date and time is not updated and go to 2003 year.

Kindly suggest what issue with the ASA.

I am not entirely sure that this is normal...As Richard has mentioned when you do a "soft" reboot the ASA goes through a series of shutdow procedures which may include taking a snapshot of the current time during reboot.

But when you change the system time on the ASA the ASA updates the system BIOS which is powered by a battery on the motherboard. So in the case of even a "hard" reboot that time should still be stored in BIOS which is powered seperately.

Before, thinking this is normal behavior, and if this is a really important issue to resolve in the case that you can not use an NTP server, I would suggest changing the battery on the motherboard, perhaps it has gone flat.
