date_default_timezone_get
(PHP 5 >= 5.1.0)
date_default_timezone_get — Gets the default timezone used by all date/time functions in a script
Description
In order of preference, this function returns the default timezone by:
-
Reading the timezone set using the date_default_timezone_set() function (if any)
-
Reading the TZ environment variable (if non empty) (Prior to PHP 5.3.0)
-
Reading the value of the date.timezone ini option (if set)
-
Querying the host operating system (if supported and allowed by the OS)
If none of the above succeed, date_default_timezone_get() will return a default timezone of UTC.
Return Values
Returns a string.
Changelog
| Version | Description |
|---|---|
| 5.3.0 | The TZ environment variable is no longer used to guess the timezone. |
Examples
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
