  \class eZLocale ezlocale.php
  \ingroup eZLocale
  \brief Provides unified access to locale information and conversions.

  The eZLocale class handles locale information and can format time, date, numbers and currency
  for correct display for a given locale. The locale conversion uses plain numerical values for
  dates, times, numbers and currency, if you want more elaborate conversions consider using the
  eZDate, eZTime, eZDateTime and eZCurrency classes.

  The first time a locale object is created (ie. eZLocale::instance() ) you must be sure to set
  a language using setLanguage before using any textual conversions.

  Example:

\code
//include_once( 'lib/ezlocale/classes/ezlocale.php' );

// Fetch the default values supplied by site.ini
$locale = eZLocale::instance();

// Make sure PHP is to the correct locale
$locale->initPHP();

print( $locale->formatTime() . '<br>' ); // Display current time
print( $locale->formatDate() . '<br>' ); // Display current day

foreach ( $locale->weekDays() as $day ) // Print a week with 3 letter daynames
{
    print( $locale->shortDayName( $day ) . '<br>' );
}
\endcode

The date and time formats are quite similar to the builtin PHP date function,
the main differences are those which returns textual representations of months
and days.
More info on the date function here:
http://www.php.net/manual/en/function.date.php

The following characters are not recognized in the format string:

- B - Swatch Internet time
- r - RFC 822 formatted date; e.g. "Thu, 21 Dec 2000 16:01:07 +0200" (added in PHP 4.0.4)
- S - English ordinal suffix for the day of the month, 2 characters; i.e. "st", "nd", "rd" or "th"

The following characters are recognized in the format string:

- a - "am" or "pm"
- A - "AM" or "PM"
- d - day of the month, 2 digits with leading zeros; i.e. "01" to "31"
- D - day of the week, textual, 3 letters; e.g. "Fri"
- F - month, textual, long; e.g. "January"
- g - hour, 12-hour format without leading zeros; i.e. "1" to "12"
- G - hour, 24-hour format without leading zeros; i.e. "0" to "23"
- h - hour, 12-hour format; i.e. "01" to "12"
- H - hour, 24-hour format; i.e. "00" to "23"
- i - minutes; i.e. "00" to "59"
- I (capital i) - "1" if Daylight Savings Time, "0" otherwise.
- j - day of the month without leading zeros; i.e. "1" to "31"
- l (lowercase 'L') - day of the week, textual, long; e.g. "Friday"
- L - boolean for whether it is a leap year; i.e. "0" or "1"
- m - month; i.e. "01" to "12"
- M - month, textual, 3 letters; e.g. "Jan"
- n - month without leading zeros; i.e. "1" to "12"
- O - Difference to Greenwich time in hours; e.g. "+0200"
- s - seconds; i.e. "00" to "59"
- t - number of days in the given month; i.e. "28" to "31"
- T - Timezone setting of this machine; e.g. "EST" or "MDT"
- U - seconds since the Unix Epoch (January 1 1970 00:00:00 GMT)
- w - day of the week, numeric, i.e. "0" (Sunday) to "6" (Saturday)
- W - ISO-8601 week number of year, weeks starting on Monday (added in PHP 4.1.0)
- Y - year, 4 digits; e.g. "1999"
- y - year, 2 digits; e.g. "99"
- z - day of the year; i.e. "0" to "365"
- Z - timezone offset in seconds (i.e. "-43200" to "43200"). The offset for timezones west of UTC is always negative, and for those east of UTC is always positive.
