DATE_DEFAULT_TIMEZONE_GET(3) 1 DATE_DEFAULT_TIMEZONE_GET(3) date_default_timezone_get - Gets the default timezone used by all date/time functions in a script SYNOPSIS
string date_default_timezone_get (void ) DESCRIPTION
In order of preference, this function returns the default timezone by: o Reading the timezone set using the date_default_timezone_set(3) function (if any) o Prior to PHP 5.4.0 only: Reading the $TZ environment variable (if non empty) o Reading the value of the date.timezone ini option (if set) o Prior to PHP 5.4.0 only: Querying the host operating system (if supported and allowed by the OS). This uses an algorithm that has to guess the time- zone. This is by no means going to work correctly for every situation. A warning is shown when this stage is reached. Do not rely on it to be guessed correctly, and set date.timezone to the correct timezone instead. If none of the above succeed, date_default_timezone_get will return a default timezone of UTC. RETURN VALUES
Returns a string. CHANGELOG

Example #1 Getting the default timezone <?php date_default_timezone_set('Europe/London'); if (date_default_timezone_get()) { echo 'date_default_timezone_set: ' . date_default_timezone_get() . '<br />'; } if (ini_get('date.timezone')) { echo 'date.timezone: ' . ini_get('date.timezone'); } ?> The above example will output something similar to: date_default_timezone_set: Europe/London date.timezone: Europe/London Example #2 Getting the abbreviation of a timezone <?php date_default_timezone_set('America/Los_Angeles'); echo date_default_timezone_get() . ' => ' . date('e') . ' => ' . date('T'); ?> The above example will output: America/Los_Angeles => America/Los_Angeles => PST SEE ALSO

DATEFMT_FORMAT(3) 1 DATEFMT_FORMAT(3) IntlDateFormatter::format - Format the date/time value as a string Object oriented style SYNOPSIS
public string IntlDateFormatter::format (mixed $value) DESCRIPTION
Procedural style string datefmt_format (IntlDateFormatter $fmt, mixed $value) Formats the time value as a string. PARAMETERS
o $fmt - The date formatter resource. o $value - Value to format. This may be a DateTime object, an IntlCalendar object, a numeric type representing a (possibly fractional) num- ber of seconds since epoch or an array in the format output by localtime(3). If a DateTime or an IntlCalendar object is passed, its timezone is not considered. The object will be formatted using the formaters configured timezone. If one wants to use the timezone of the object to be formatted, IntlDateFormatter.setTimeZone(3) must be called before with the objects timezone. Alterna- tively, the static function datefmt_formatObject(3) may be used instead. RETURN VALUES
The formatted string or, if an error occurred, FALSE. CHANGELOG
