TIMESTAMP inserting wrong date in database when run from PHP

I have a insert query from PHP file to database.

While executing the query from MySQL Workbench it is inserting last_used value in database exact time given in the query. But when I try to run the same query from PHP code it is inserting 1 day future date.

In both scenarios created_at inserting correct value which is mentioned in the table structure

I have set timezone to Asia/Kolkata in php.ini file.

I have searched a lot in the google and executed all the things mentioned by all.

<?php
$servername = "localhost";
$username = "user";
$password = "password";
$dbname = "db";

// Create connection
$conn = new mysqli($servername, $username, $password, $dbname);
// Check connection
if ($conn->connect_error) {
  die("Connection failed: " . $conn->connect_error);
}

$sql = "INSERT INTO `login_token` (`userid`, `username`, `token`, `last_used`, `role_id`) VALUES ('aiIRX+5v35p4vOokrgVR+Q==', '/McgiDGM0JpsyCSie2cIV4sTwrtkE+ev', 'token1', '2022-09-19 12:47:59', '')";

if ($conn->query($sql) === TRUE) {
  echo "New record created successfully";
} else {
  echo "Error: " . $sql . "<br>" . $conn->error;
}
?>
