Php different timezones [closed]

Question

I'm developing a web app in php mysql which should be usable in the whole world. In this app there is a big usage of time so I'm wondering if there is any work to do on the timezones differences or if php is automatically recognizing the different timezones before saving in the db ?

Thanks for your help

Answer 1

MySQL Server Time Zone Support

And ensure that you store all dates and times in the database in UTC. It's the only way to remain sane.

Answer 2

You can create a function for geting time zone for differenct places

function getDatetimeNow() {

$tz_object = new DateTimeZone('Asia/Karachi');
//date_default_timezone_set('Brazil/East');
$datetime = new DateTime();
$datetime->setTimezone($tz_object);
return $datetime->format('Y\-m\-d\ h:i:s');   

}
