The script needs a Linux current version of the date command to do all the time cleverness. Don't expect it to work with ancient Solaris, etc, date commands!
It runs on the nagios server and does an snmp get to a remote server to get the date and time, and compares against the date and time on the nagios server.
$ /usr/local/nagios/libexec/snmp_remote_time_utc -H zrhnora04a1 -C public -w 30 -c 60
TIME OK - Time difference = -5s|diff=-5
Here our UK nagios server is checking the time on a server in Zurich. It reports the Zurich server is 5 seconds slower than the nagios server. Since its below the warning threshold of 30 seconds its ok.

Thanks for the plugin, this is the best one!
Here are two remarks:
1. It doesn't work for Windows and ESXi as they don't provide zone information by SNMP.
2. Timeout should be changed from 60 seconds and 5 retries to 30 second and single retry in order not to get CRITICAL instead of WARNING:
