Is there a way to get user's timezone using PHP?

[imgrooot]

I was wondering if there is a way to automatically get a user's timezone? I want to show certain information if the user's current date is less than the expiry date. It works fine if the user is in a default timezone but what if the user is in a different timezone? How I can I make sure I can get their correct current time?

date_default_timezone_set('America/New_York');

$expiry_date     = trim($row['expiry_date']);
$current_date    = date('Y-m-d H:i:s');

if($current_date < $expiry_date) {
  // show data
} else {
  // don't show
}

No, there is no way to get the client's timezone with PHP. As you probably know, PHP runs on the server, and the HTTP requests sent by the clients don't contain any timezone information.

 

What you can do is try to get the timezone with JavaScript or make the user explicitly select their timezone. You can also use the IP address and a geolocation database to make an educated guess (but you still need a way for the user to correct the information).

Got it. Thanks.
