If you have ntp on each server, and configure it correctly, you could 
use check_ntp -H remote_server -w 15 to test if it's out of sync with 
the Nagios server

The on the nagios server itself have the same check but against the real 
ntp server, this way you've got a chain of correct times or not.

Not ideal, but one possible workaround.

Other ideas could be SNMP on the remote hosts, or NSCA to feed back to 
the nagios server...
