Time is a standard protocol. Its status is elective. The current TIME specification can be found in RFC 868 - Time Server Protocol.
Daytime is a standard protocol. Its status is elective. The current daytime specification can be found in RFC 867 - Daytime Protocol.
The time protocol provides a machine-readable date and time. It uses TCP or UDP as the transport vehicle. Port 37 (decimal) is used.
The 32-bit number represents the number of elapsed seconds since midnight on January 1st 1900 (GMT). It is suitable for a machine to set its own clock to this, but it is not very human-readable.
The daytime protocol is similar in concept, but the server will now send a readable ASCII character string back to the client. The format of this ASCII string is not formalized. Port 13 (decimal) is used for this protocol.
AIX/6000 provides both the client and server functions. The server function is included in the base inetd process; the client part is provided through the setclock command.
TCP/IP for DOS provides the client function with the setclock command.
