public final class: rdate [javadoc | source]

java.lang.Object
   examples.rdate

This is an example program demonstrating how to use the TimeTCPClient and TimeUDPClient classes. It's very similar to the simple Unix rdate command. This program connects to the default time service port of a specified server, retrieves the time, and prints it to standard output. The default is to use the TCP port. Use the -udp flag to use the UDP port. You can test this program by using the NIST time server at 132.163.135.130 (warning: the IP address may change).

Usage: rdate [-udp]
