(PHP 5 >= 5.1.0)
date_default_timezone_get — Gets the default timezone used by all date/time functions in a script
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.
Returns a string.
| Version | Description |
|---|---|
| 5.3.0 | The TZ environment variable is no longer used to guess the timezone. |
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
