NAME
   Date::Extract - extract probable dates from strings

VERSION
   Version 0.02 released 13 Feb 08

SYNOPSIS
       my $parser = Date::Extract->new();
       my $dt = $parser->extract($arbitrary_text)
           or die "No date found.";
       return $dt->ymd;

MOTIVATION
   There are already a few modules for getting a date out of a string.
   DateTime::Format::Natural should be your first choice. There's also
   Time::ParseDate which fits some very specific formats. Finally, you can
   coerce Date::Manip to do your bidding.

   But I needed something that will take an arbitrary block of text, search
   it for something that looks like a date string, and build a DateTime
   object out of it. This module fills this niche. By design it will
   produce few false positives. This means it will not catch nearly
   everything that looks like a date string. So if you have the string "do
   homework for class 2019" it won't return a DateTime object with the year
   set to 2019.

METHODS
 new PARAMHASH => "Date::Extract"
  arguments
   time_zone
       Forces a particular time zone to be set (this actually matters, as
       "Tuesday" on Monday at 11 PM means something different than
       "Tuesday" on Tuesday at 1 AM).

       By default it will use the "floating" time zone. See the
       documentation for DateTime.

       This controls both the input time zone and output time zone.

   prefers
       This argument decides what happens when an ambiguous date appears in
       the input. For example, "Friday" may refer to any number of Fridays.
       The valid options for this argument are:

       nearest
           Prefer the nearest date. This is the default.

       future
           Prefer the closest future date.

       past
           Prefer the closest past date. NOT YET SUPPORTED.

   returns
       If the text has multiple possible dates, then this argument
       determines which date will be returned. By default it's 'first'.

       first
           Returns the first date found in the string.

       last
           Returns the final date found in the string.

       earliest
           Returns the date found in the string that chronologically
           precedes any other date in the string.

       latest
           Returns the date found in the string that chronologically
           follows any other date in the string.

       all Returns all dates found in the string, in the order they were
           found in the strong.

       all_cron
           Returns all dates found in the string, in chronological order.

       This method will combine the arguments of parser->new and extract.
       Modify the "to" hash directly.

 extract, ARGS text => "DateTime"s
       Takes an arbitrary amount of text and extracts one or more dates
       from it. The return value will be zero or more "DateTime" objects.
       If called in scalar context, only one will be returned, even if the
       "returns" argument specifies multiple possible return values.

       See the documentation of "new" for the configuration of this method.
       Any arguments passed into this method will trump those from the
       parser.

       You may reuse a parser for multiple calls to "extract".

       You do not need to have an instantiated "Date::Extract" object to
       call this method. Just "Date::Extract->extract($foo)" will work.

       DateTime::Format::Natural. We still use it, but it doesn't quite
       fill all the particular needs we have.
