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

Opis

string date_default_timezone_get ( void )

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)
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.

Zwracane wartości

Returns a string.

If you want to get the abbrivation (3 or 4 letter), instead of the long timezone string you can use date('T') function like this:



Input:

date_default_timezone_set('America/Los_Angeles');

echo date_default_timezone_get();

echo ' => '.date('e');

echo ' => '.date('T');



Output:

America/Los_Angeles => America/Los_Angeles => PST

date_default_timezone_get() will still emit a warning in E_STRICT if the timezone is not set; either by date_default_timezone_set() or the ini option of date.timezone.



This is probably not a big deal, but I thought I would contribute what I found.
