# ptktime(1)

Perl/Tk Time Client for X

## NAME

ptktime - Perl/Tk Time Client for X

## SYNOPSIS

**ptktime** \[*timeserver*\]

## DESCRIPTION

*ptktime* is a time (TCP port 37) client for X, written in Perl/Tk.

It will compare your system's time with a timeserver on another machine.

### OPTIONS

- **timeserver**

  The remote timeserver to compare times with.

## REQUIREMENTS

ptktime requires a fairly up-to-date version of Perl (version 5.002 or better). It also (obviously) requires Perl/Tk. Perl/Tk is available in the Nick-Ing Simmons author directory at CPAN. It is also available as a Debian package.

## AUTHOR and BUG REPORTING

ptktime was written by Alan Ford \<alan@whirlnet.co.uk\> Please report bugs to that address.

## SEE ALSO

[inetd(8)](/inetd/8.md), [telnet(1)](/telnet/1.md), perl-tk documentation.

The time (port 37) protocol is defined in RFC868.

A related protocol, daytime, is defined in RFC867.

## FUTURE PLANS

At some time I intend to include the facility to set the local machine time to the timeserver's time.
