=head1 NAME

DateTime::Format::Flexible::lang::en - the english language plugin

=head1 DESCRIPTION

You should not need to use this module directly.

If you only want to use one language, specify the lang property when parsing a date.

example:

 my $dt = DateTime::Format::Flexible->parse_datetime(
     'Wed, Jun 10, 2009' ,
     lang => ['en']
 );
 # $dt is now 2009-06-10T00:00:00

Note that this is not required, by default ALL languages are scanned when trying to parse a date.

=head2 new

Instantiate a new instance of this module.

=head2 months

month name regular expressions along with the month numbers (Jan(?:uary)? => 1)

=head2 days

day name regular expressions along the the day numbers (Mon(?:day)? => 1)

=head2 day_numbers

maps day of month names to the corresponding numbers (first => 01)

=head2 hours

maps hour names to numbers (noon => 12:00:00)

=head2 remove_strings

strings to remove from the date (rd as in 3rd)

=head2 parse_time

searches for the string 'at' to help determine a time substring (sunday at 3:00)

=head2 string_dates

maps string names to real dates (now => DateTime->now)

=head2 relative

parse relative dates (ago => ago, from => from now, next => next, last => last)

=head2 math_strings

useful strings when doing datetime math

=head2 timezone_map

maps unofficial timezones to official timezones for this language (CST => America/Chicago)
