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.
