It's most often used for testing network connections. Rarely does anyone need this service. Echo simply echoes whatever it receives on the network. Again, good for testing netowkr connections but not very useful for most people. I think that time will send the unix time (sec since 1970) to whatever connections it receives. I'm not really certain about this one. Daytime will send a human readable string containing the current time, such as "19 MAY 2003 20:02:05 EDT". None of these services are going to cause you much grief if you disable them (of course this is only my best guess).
