NAME

       dp - nmh parser of RFC 822-style dates

SYNOPSIS

       /usr/lib/mh/dp [-help] [-version] [-form formatfile] [-format string] [-width columns]
            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 nmh 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 quotes for
       the shell.

       To override the output format used by dp, the -format string or -format file switches  are
       used.   This  permits  individual  fields  of  the address to be extracted with ease.  The
       string is simply a format string and the file is simply a format file.   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 RFC 822-proper format of the date.
