date@ 1 user commands djbwares
date@ prints the date on a remote host.
`date@` host

## Description

`date@` uses tcpclient 1 to connect to TCP port 13 on host and prints any data that it receives. It uses delcr 1 and cat 1 to remove CR (\015) and convert unprintable characters to a visible format.

If host is not supplied, `date@` connects to the local host.

TCP port 13 is the well-known port for the Daytime service. Some computers respond to connections on this port with a human-readable date. For example, they may be running `tcpserver -R -H -l0 0 13 date` using tcpserver 1.

## History

`date@` was originally part of Daniel J. Bernstein's ucspi-tcp toolset in 1999.
