NAME

  dp - parse dates RFC 822-style

SYNOPSIS

  /usr/lib/mh/dp [-form	file] [-format string] [-help] [-width columns]	dates

OPTIONS

  -form	file
      Overrides	the default output format of dp.  The output is	formatted
      according	to the instructions in the specified file.  This must be a
      format file; see mh-format(4).

  -format string
      Overrides	the default output format of dp.  The output is	formatted
      according	to the instructions in the specified string.  This must	be a
      format string; see mh-format(4).

      The argument to the -format option must be interpreted as	a single
      token by the shell that invokes dp. Therefore, you should	usually	place
      the argument to this option inside double	quotes (").

  -help
      Prints a list of the valid options to this command.

  -width columns
      Specifies	the width of the screen	in columns.

  The defaults for this	command	are as follows:

       -width  defaults	to the width of	the terminal

DESCRIPTION

  The dp command parses	dates according	to the ARPA Internet standard.	It
  also understands many	non-standard formats, such as those produced by
  TOPS-20 sites	and some UNIX sites using ctime(3). It is useful for seeing
  how MH will interpret	a date.

  The dp program treats	each argument as a single date,	and prints the date
  out in the official RFC 822 format. Hence, it	is usually best	to enclose
  each argument	in double quotes (") for the shell.

EXAMPLES

  This is the default format string used by dp:

       %<(nodate{text})error: %{text}%|%(pretty{text})%>

  When an error	is detected, this prints error:	and the	date that is in
  error. Otherwise, it outputs the proper RFC 822 format of the	date.
