How to fix warning from date() in PHP"

Posted by: admin April 23, 2020 Leave a comment


I am using XAMPP(PHP Version 5.3.1) on winxp. When I try to call time() or date() function on my localhost. It will show warning message as this,

Severity: Warning

Message: date() [function.date]: It is
not safe to rely on the system’s
timezone settings. You are required
to use the date.timezone setting or
the date_default_timezone_set()
function. In case you used any of
those methods and you are still
getting this warning, you most likely
misspelled the timezone identifier. We
selected ‘UTC’ for ‘8.0/no DST’

Filename: helpers/date_helper.php

How can I disable the warning? Thanks.

How to&Answers:

Try to set date.timezone in php.ini file. Or you can manually set it using ini_set() or date_default_timezone_set().


You need to set the default timezone smth like this :


More info about this in http://php.net/manual/en/function.date-default-timezone-set.php

Or you could use @ in front of date to suppress the warning however as the warning states it’s not safe to rely on the servers default timezone


You could also use this:


You should call this before calling any date function. It accepts the key as the first parameter to alter PHP settings during runtime and the second parameter is the value.

I had done these things before I figured out this:

  1. Changed the PHP.timezone to “Asia/Calcutta” – but did not work
  2. Changed the lat and long parameters in the ini – did not work
  3. Used date_default_timezone_set("Asia/Calcutta"); – did not work
  4. Used ini_alter() – IT WORKED
  5. Commented date_default_timezone_set("Asia/Calcutta"); – IT WORKED
  6. Reverted the changes made to the PHP.ini – IT WORKED

For me the init_alter() method got it all working.

I am running Apache 2 (pre-installed), PHP 5.3 on OSX mountain lion


This just happen to me because
in the php.ini the date.timezone was not set!


Using the php date() function triggered that warning.


error_reporting(E_ALL ^ E_WARNING);
