dp(8)
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.

FILES
  $HOME/.mh_profile
      User profile.
