How to change the default timezone in PHP

Looking for Linux Server Admin or WordPress Expert? We can help.

The default timezone for PHP is defined in php.ini configuration file. So you will need to edit the file manually for changing it.

You can find the location of your php.ini file on your server/system by running below command on terminal.

php --ini


In this example, it is found at /etc/php5/cli/php.ini

Next, find out the timezone (TZ) string of your region. For that, you can use a command-line tool called tzselect. Simply run the following command:



Once you have selected a continent or ocean, tzselect will print the value of TZ variable as follows. In this example, the TZ value is “Asia/Kolkata”.



Now open up php.ini in a text editor.

Then look up “date.timezone” variable in it.

If “date.timezone” variable definition is commented out, uncomment the line (to uncomment the line, remove the semicolon from the beginning of that line). Then change the timezone accordingly.

date.timezone = "Asia/Kolkata"

You are done!
