NAME

       dp - parse dates 822-style


SYNOPSIS

       /usr/lib/nmh/dp [-form formatfile]
            [-format string] [-width columns] dates ...
            [-version] [-help]


DESCRIPTION

       Dp  is a program that parses dates according to the ARPA Internet stan-
       dard.  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  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  `-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 822-proper format of the
       date.

BUGS

       The argument to the `-format' switch must be interpreted  as  a  single
       token  by the shell that invokes dp.  Therefore, one must usually place
       the argument to this switch inside double-quotes.
