Change Apache/PHP timezone

When creating websites, you may need to modify the timezone for Apache/PHP. There are two ways – you can set the timezone in the .hatccess file or in a PHP file (index.php or another file that will be loaded first).

In the .htaccess file use SetEnv TZ <timezone> to set the enviromental value TZ

//examples
SetEnv TZ Asia/Manila
SetEnv TZ America/Fort_Nelson

You can also set here the date.timezone PHP value with php_value date.timezone “<timezone>”

php_value date.timezone "America/Cayenne"

To set the default timezone in a PHP file use the code:

<?php
date_default_timezone_set('America/Denver');

//
?>

You can also set in PHP the enviromental variable TZ

<?php
putenv("TZ=Africa/Accra");
?>

If your host allow the use of .ini file you can set the timezone in such a file

date.timezone = "Africa/Cairo"
