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 value of the date.timezone ini option (if set)
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.
This function has no parameters.
Returns a string.
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
