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 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.

`-format' default as described above
`-width' default to the width of the terminal
None
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.
