5 dp \- parse dates 822-style
14 \fIDp\fR is a program that parses dates according to the ARPA Internet
16 It also understands many non\-standard formats,
17 such as those produced by TOPS\-20 sites and some UNIX sites using
19 It is useful for seeing how \fIMH\fR will interpret a date.
21 The \fIdp\fR program treats each argument as a single date,
22 and prints the date out in the official 822\-format.
23 Hence, it is usually best to enclose each argument in double\-quotes for the
26 To override the output format used by \fIdp\fR,
27 the `\-format\ string' or `\-format\ file' switches are used.
28 This permits individual fields of the address to be extracted with ease.
29 The string is simply a format stringand thefile is simply a format file.
30 See \fImh\-format\fR\0(5) for the details.
32 Here is the default format string used by \fIdp\fR:
36 %<(nodate{text})error: %{text}%|%(putstr(pretty{text}))%>
39 which says that if an error was detected, print the error, a `:',
40 and the date in error.
41 Otherwise, output the 822\-proper format of the date.

51 `\-format' default as described above
53 `\-width' default to the width of the terminal
57 The argument to the `\-format' switch must be interpreted as a single token
58 by the shell that invokes \fIdp\fR.
60 one must usually place the argument to this switch inside double\-quotes.
