You can't get a user's timezone on the server side, and you can only make a guess at it on the client side.

您无法在服务器端获取用户的时区,并且您只能在客户端猜测它。

If you rely on getting the user's IP address then you could geolocate that and deduce a time.

如果您依赖于获取用户的IP地址,那么您可以对其进行地理定位并推断出时间。

The way this is usually done is by asking the user (when they register, for instance) what timezone they are in and then use this in your time calculations.

通常这样做的方法是询问用户(例如他们何时注册)他们所在的时区,然后在计算时间中使用它。

For geolocation you can use http://ipinfodb.com/, work great with an API!

对于地理定位,您可以使用http://ipinfodb.com/,与API配合使用!

function GeoLocation($precision='city',$ip,$api) {

    if($precision == "country") {
        $file = "ip_query_country.php";
    }
    else {
        $file = "ip_query.php";
    }

    $params = @file_get_contents("http://api.ipinfodb.com/v2/ip_query.php?key=".$api."&ip=".$ip."&timezOne=true");
    $fields = @new SimpleXMLElement($params);
    foreach($fields as $field => $val) {
        $result[(string)$field] = (string)$val;
    }
    return $result;
}

With a small "cheating" (using client side scripting) and posting the result to your server, you can access your client's timezone.

通过小的“作弊”(使用客户端脚本)并将结果发布到您的服务器,您可以访问客户端的时区。

For example you can use this Javascript library:

例如,您可以使用此Javascript库:

https://bitbucket.org/pellepim/jstimezonedetect

var tz = jstz.determine(); // Determines the time zone of the browser client
tz.name(); // Returns the name of the time zone eg "Europe/Berlin"

The most reliable method is to ask the user to set his own timezone. I think it's a good idea to have a timestamp of when the users account was created in your own database for your own use.

最可靠的方法是要求用户设置自己的时区。我认为在您自己的数据库中创建用户帐户的时间戳是一个好主意,供您自己使用。

These are the steps I would take to have a users timezone:

这些是我用来拥有用户时区的步骤:

1- Preserve the timestamp column that you have for your own usage
2- Add a new column for the actual users timezone
3- Use Javascript to retrieve the timezone:
new Date().getTimezoneOffset()/60;

4- Also allow users to set there own timezone as well

1-保留您自己使用的时间戳列2-为实际用户时区添加新列3-使用Javascript检索时区:new Date()。getTimezoneOffset()/ 60;
4-还允许用户设置自己的时区

You can also take it a step further and use a geo-location service to detect a users timezone.

您还可以更进一步,使用地理位置服务来检测用户时区。
