Check & report time on switch and synchronize with other devices

Hi,

I would like  to ensure the time on our servers are correct.Please suggest the method that you think is the best fit.we have to make sure that:

1) The time provided by our core switch is matching with other domain servers.(Note: this is a Cisco 6509 core network switch).

2) The time on the switch matches the time on all other servers. I tried to use the below script but that didn't help, I guess we need to get this using SNMP/WMI protocols, could you suggest any script that could do the trick. I do not have any idea on this, this would be a great help if you could suggest a solution.

Thanks in advance,

Ashish
