DP(8)DP(8)NAMEdp - parse dates RFC 822-style
SYNOPSIS
/usr/local/libexec/nmh/dp [-form formatfile] [-format string] [-width
columns] [-version] [-help] dates ...
DESCRIPTION
Dp is a program that parses dates according to the ARPA Internet stan‐
dard. 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 RFC 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:
%<(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 RFC 822-proper format of the
date.
