- UDP or TCP daytime protocol service daemon
The in.daytimed service provides the server-side of the daytime protocol. This protocol is used for debugging and bandwidth measurement and is available on both TCP and UDP transports, through port 13.
Once a connection is established, the in.daytimed generates the current date and time in ctime(3C) format as 7-bit ASCII and sends it through the connection. The server then closes the connection. Any data received from the client side of the connection is discarded.
The in.daytimed listens for UDP datagrams. When a datagram is received, the server generates the current date and time in ctime(3C) format as 7-bit ASCII and inserts it in a UDP datagram sent in response to the client's request. Any received data is ignored.
