DateTime::Locale::Base(3)

NAME
DateTime::Locale::Base - Base class for individual locale objects (deprecated)

VERSION
version 1.45

SYNOPSIS
  use base 'DateTime::Locale::Base';

DESCRIPTION
This module is no longer used by the code in the distribution. It is still included for the sake of any code out in the wild that may subclass this class. This class will be removed in a future release.

DEFAULT FORMATS
Each locale has a set of four default date and time formats. They are distinguished by length, and are called "full", "long", "medium", and "short". Each locale may have a different default length which it uses when its "$locale->date_format_default()", "$locale->time_format_default()", or "$locale->datetime_format_default()" methods are called.

This can be changed by calling the "$locale->set_default_date_format()" or "$locale->set_default_time_format()" methods. These methods accept a string which must be one of "full", "long", "medium", or "short".

NAME FORMS
Most names come in a number of variations. First, they may vary based on length, with wide, abbreviated, and narrow forms. The wide form is typically the full name, while the narrow form is often a single character. The narrow forms may not be unique. For example, "T" may be used for Tuesday and Thursday in the English narrow forms.

Many names also distinguish between "format" and "stand-alone" forms of a pattern. The format pattern is used when the thing in question is being placed into a larger string. The stand-alone form is used when displaying that item by itself, for example in a calendar.
