Thanks a lot for all your replies. Its an interesting note to take a look at dsh, that will help a lot on retrieval of system information which can be run on parallel. Apparently, our Security Group, wouldn't allow us to use it due to some "security" concerns but its is best to use this tool somewhere else or other environment.

What I did for now is to create a script and like what other folks suggested, use epoch time as the baseline and do public key authentication to remote servers one by one and compare the date and time. There will be a second delayed so I put in my script to check clock times which are more than 3 seconds or less than 0 second and assume that time is not sync.

SSH-COPY-ID(1)						      General Commands Manual						    SSH-COPY-ID(1)

NAME
ssh-copy-id - install your public key in a remote machine's authorized_keys SYNOPSIS
ssh-copy-id [-i [identity_file]] [user@]machine DESCRIPTION
ssh-copy-id is a script that uses ssh to log into a remote machine (presumably using a login password, so password authentication should be enabled, unless you've done some clever use of multiple identities) It also changes the permissions of the remote user's home, ~/.ssh, and ~/.ssh/authorized_keys to remove group writability (which would oth- erwise prevent you from logging in, if the remote sshd has StrictModes set in its configuration). If the -i option is given then the identity file (defaults to ~/.ssh/id_rsa.pub) is used, regardless of whether there are any keys in your ssh-agent. Otherwise, if this: ssh-add -L provides any output, it uses that in preference to the identity file. If the -i option is used, or the ssh-add produced no output, then it uses the contents of the identity file. Once it has one or more fin- gerprints (by whatever means) it uses ssh to append them to ~/.ssh/authorized_keys on the remote machine (creating the file, and directory, if necessary) SEE ALSO
