NAME
DateTime::Format::Flexible::lang::de - german language plugin
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(
'Montag, 6. Dez 2010' ,
lang => ['de']
);
# $dt is now 2010-12-06T00:00:00
Note that this is not required, by default ALL languages are scanned when trying to parse a date.
new
Instantiate a new instance of this module.
months
month name regular expressions along with the month numbers (Jan(:?uar)? => 1)
days
day name regular expressions along the the day numbers (Montag => 1)
day_numbers
maps day of month names to the corresponding numbers (erster => 01)
hours
maps hour names to numbers (Mittag => 12:00:00)
remove_strings
strings to remove from the date (um as in um Mitternacht)
parse_time
string_dates
maps string names to real dates (jetzt => DateTime->now)
ago
the word use to denote a date in the past (vor 3 Jahren => 3 years ago)
math_strings

timezone_map
maps unofficial timezones to official timezones for this language (MEZ => Europe/Berlin)
