DAYTIME
From Wikipedia, the free encyclopedia
The DAYTIME service is an Internet protocol defined in RFC 867. It is intended for testing and measurement purposes.
A host may connect to a server that supports the DAYTIME protocol, on either TCP or UDP port 13. The server then returns the current date and time as an ASCII string with an unspecified format.
Current testing and measurement of IP networks is more commonly done with ping and traceroute.
