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’ 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.
