DP(8) [nmh-1.0.4] (MH.6.8) DP(8)
NAME
dp - parse dates 822-style
SYNOPSIS
/usr/freeware/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 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.

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.
