- Daytime Protocol
-
-
-
-
- This RFC specifies a standard for the ARPA Internet community. Hosts on
- the ARPA Internet that choose to implement a Daytime Protocol are
- expected to adopt and implement this standard.
-
- 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.
-
- TCP Based Daytime Service
-
- One daytime service is defined as a connection based application on
- TCP. A server listens for TCP connections on TCP port 13. Once a
- connection is established the current date and time is sent out the
- connection as a ascii character string (and any data received is
- thrown away). The service closes the connection after sending the
- quote.
-
- UDP Based Daytime Service
-
- Another daytime service service is defined as a datagram based
- application on UDP. A server listens for UDP datagrams on UDP port
- 13. When a datagram is received, an answering datagram is sent
- containing the current date and time as a ASCII character string (the
- data in the received datagram is ignored).
-
- Daytime Syntax
-
- There is no specific syntax for the daytime. It is recommended that
- it be limited to the ASCII printing characters, space, carriage
- return, and line feed. The daytime should be just one line.
-
- One popular syntax is:
-
- Weekday, Month Day, Year Time-Zone
-
- Example:
-
- Tuesday, February 22, 1982 17:37:43-PST

- RFC 867 May 1983
- Daytime Protocol
-
-
- Another popular syntax is that used in SMTP:
-
- dd mmm yy hh:mm:ss zzz
-
- Example:
-
- 02 FEB 82 07:59:01 PST
-
- NOTE: For machine useful time use the Time Protocol (RFC-868).
