将时区设置为客户端的本地时间

Question

我在托管服务提供商“byethost.com”上加载了我的 php 脚本。我正在尝试将 created_at 中记录的时间设置为客户端的本地时间，但我总是得到 GTM 时间。我怎样才能让它工作？

 <?php
 $data = json_decode ( file_get_contents ( 'php://input', true ) );

$mac = $data->{'mac'};
$latitude = $data->{'latitude'};
$longitude = $data->{'longitude'};
$route =   $data->{'route'};

$timeZone = "Europe/Berlin";
$print = date_default_timezone_set($timeZone);

$con = new mysqli ( "domin.com", "username", "password", "database" );


// check whether route's table exist.
$results = $con->query ( "SHOW TABLES like 'bus' " ) or die ( mysqli_error () );

if (($results->num_rows) == 1) {$sql = "REPLACE INTO bus(mac, route, latitude, longitude, created_at)
          VALUES( ?, ?, ? , ?, ? )";
  $stmt = $con->prepare($sql);

  if(false === $stmt){
    echo "prepare()  failed: ";
  }

  $rc = $stmt->bind_param("sssss",$mac,$route, $latitude,$longitude, $print);
 echo $rc;
  if ( false===$rc ) {
  echo "bind_param() failed: ";
}

  $rc = $stmt->execute();

  if ( false===$rc ) {
 echo "execute failed.";
  }

  $stmt->close();

} else {
  $create =  "CREATE TABLE bus
       (id INT(11) NOT NULL AUTO_INCREMENT PRIMARY KEY,
        mac VARCHAR(30) NOT NULL UNIQUE,
        route int(11) ,
     latitude FLOAT(10,6) NOT NULL , 
     longitude FLOAT(10,6) NOT NULL,
     created_at TIMESTAMP NOT NULL" ;
   $stmt = $con->prepare($create) or die ( $con->error );
  $stmt->execute();

  $stmt->close();

}

也许可以试试这个？

date_default_timezone_set($timeZone);

时区可以是：

"Europe/Oslo"
