while($chat = $result->fetch_object()){ // Returning the GMT (UTC) time of the chat creation: $chat->time = array( 'hours' => date('H',strtotime($chat->ts)), 'minutes' => date('i',strtotime($chat->ts)) );
I'm using this code to display time alongside chat message. How can I change this code to display output time in IST timezone? Thank you

You've several ways to achieve this, a simple one is using date_default_timezone_set before date, i.e.:
date_default_timezone_set('Asia/Kolkata');answered May 22, 2017 at 20:08

Để giải quyết vấn đề này có nhiều cách, tuy nhiên trong chuyên đề này mình đi về time trong php nên mình sẽ dùng luôn hàm set lại muối giờ:.
Nếu bạn muốn thay đổi cấu hình múi giờ cho PHP script, bạn có thể chèn đoạn mã sau vào phần mã PHP của bạn:
<?php
\\ echo “Original Time: “. date(“h:i:s”).”\n”;
putenv(“TZ=US/Eastern”);
\\ echo “New Time: “. date(“h:i:s”).”\n”;
?>
Danh sách các mã múi giờ để sử dụng thay cho giá trị “US/Eastern” trong hàm putenv() có thể tìm thấy ở đây.
