NAME

       dp - parse dates 822-style

SYNOPSIS

       /usr/lib/mmh/dp [-form formatfile] [-Version] [-help] dates ...

DESCRIPTION

       Dp  is  a  program  that  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 mmh will interpret a date.

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

       To  override  the  output  format used by dp, the -form file switch is used.  This permits
       individual fields of the address to be extracted with ease.  The file is either  the  name
       of  a  format  file or a format string directly, if prepended with an equal sign `='.  See
       mh-format(5) for the details.

       Here is the default format string used by dp:

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

       which says that if an error was detected, print the error, a `:', and the date  in  error.
       Otherwise, output the 822-proper format of the date.
