NAME
       dp - nmh	parser of RFC 822-style	dates

SYNOPSIS
       /usr/local/libexec/nmh/dp [-help] [-version] [-form formatfile] [-for-
	    mat	string]	[-width	columns] dates ...

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	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.
