- \fIDp\fR 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
- \fIctime\fR\0(3).
- It is useful for seeing how \fIMH\fR will interpret a date.
-
- The \fIdp\fR 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 \fIdp\fR,
- 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 stringand thefile is simply a format file.
- See \fImh\-format\fR\0(5) for the details.
-
- Here is the default format string used by \fIdp\fR:
-
- .ti +.5i
- %<(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.

- The argument to the `\-format' switch must be interpreted as a single token
- by the shell that invokes \fIdp\fR.
- Therefore,
- one must usually place the argument to this switch inside double\-quotes.
