DESCRIPTION

13       Dp is a program that parses dates according to the ARPA Internet  stan‐
14       dard.   It  also  understands  many non-standard formats, such as those
15       produced by TOPS-20 sites and some UNIX sites using  ctime(3).   It  is
16       useful for seeing how nmh will interpret a date.
17
18       The  dp  program  treats each argument as a single date, and prints the
19       date out in the official 822-format.  Hence,  it  is  usually  best  to
20       enclose each argument in double-quotes for the shell.
21
22       To override the output format used by dp, the -format string or -format
23       file switches are used.  This permits individual fields of the  address
24       to  be  extracted  with ease.  The string is simply a format string and
25       the file is simply a format file.  See mh-format(5) for the details.
26
27       Here is the default format string used by dp:
28
29            %<(nodate{text})error: %{text}%|%(putstr(pretty{text}))%>
30
31       which says that if an error was detected, print the error, a  `:',  and
32       the  date  in  error.   Otherwise,  output the 822-proper format of the
33       date.

BUGS

58       The argument to the -format switch must  be  interpreted  as  a  single
59       token  by the shell that invokes dp.  Therefore, one must usually place
60       the argument to this switch inside double-quotes.
