RE: Regarding Cisco Router clock

Yugandhar,

Some platforms have a hardware clock that is separate from the software clock. In Cisco IOS software syntax, the hardware clock is called the "calendar." The hardware clock is a battery-powered chip that runs continuously, even if the router is powered off or rebooted. After you set the hardware clock, the software clock will be automatically set from the hardware clock when the system is restarted or when the clock read-calendar EXEC command is issued. The time specified in this command is relative to the configured time zone.

However I've just tried this on my 3745's and the command is not available. Have you considered using an NTP service? Either the ones available from the likes of Galleon (http://www.galleon.eu.com/NTP.htm) or public NTP sources a list of which can be found at http://www.eecis.udel.edu/~mills/ntp/clock1a.html but I couldn't see one in India and I have found that some of the public NTP servers can disappear without warning

If you have any other questions give me a shout
