DP(8)DP(8)NAMEdp - parse dates 822-style
SYNOPSIS
/usr/contrib/mh/lib/dp [-form formatfile]
[-format string] [-width columns] dates ...
[-version] [-help]
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.

DP(8)DP(8)BUGS
The argument to the `-format' switch must be interpreted
as a single token by the shell that invokes dp. There-
fore, one must usually place the argument to this switch
inside double-quotes.
