rdate - get the time via the network  


rdate [-p] [-s] [-u] [-l] [-t sec] [host...]  


rdate connects to an RFC 868 time server over a TCP/IP network, printing the returned time and/or setting the system clock.  


Print the time returned by the remote machine.
Set the system time to the returned time.
Use UDP instead of TCP as the transport.
Use syslog to output errors (cron.warning) and output (cron.info).
Set timeout in seconds for every attempt to retreive date.
