When run with no options, will report the time from the                         
default network timeserver.                                                     
                                                                                
The default nework timeserver is 'time.nist.gov'.                               
(use the -t option to change the timeserver)                                    
                                                                                
Other time servers known to sometimes work:

These servers no longer seem to work (they may not support                      
the older network time request format):

          set the time to the server's time IMMEDIATELY
