purpose of Daytime servers

Question

Can someone please tell me what is the purpose of daytime servers? I referred to some sites like wikipedia, but couldn't find an answer.

Answer 1

The Daytime Protocol is for computers to communicate a widely accepted known format RFC 867 allowing the 2 computer systems to agree on the exact time and date to the current second.

Answer 2

Its not a server its a protocol that might be supported by a server. Daytime Protocol works over TCP or UDP

A useful debugging and measurement tool is a daytime service. A daytime service simply sends a the current date and time as a character string without regard to the input.
