dp8

Usage

Overview

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 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:

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.
