服务器和客户端之间的时区差异？ [英] Timezone diff between server and client?
问题描述
场景：
服务器系统遍布全球。
客户端计算机上的网页正在请求数据。
问题：
如何知道任何服务器和任何客户机之间的时区偏移？
工作：
Scenario:
Servers systems are all over the world.
Web page on the client machine is requesting data.
Issue:
How to know the time zone offset between any server and any client machine?
Work:
var DocumentTime = new Date();
function GetTimeZoneOffset()
{
var nTime = DocumentTime.getTime();
var sUrl = xxxPhpUrl + '?TimeZoneOffSet=' + nTime;
if(window.XMLHttpRequest)
{
var xhr = new XMLHttpRequest();
xhr.open("GET", sUrl, true);
xhr.onreadystatechange = function()
{
if (xhr.readyState == 4)
{}
}
xhr.timeout = 30000;
xhr.ontimeout = TimeOut;
xhr.send(null);
}
nNow = null;
nTime = null;
sUrl = null;
}
<body önload="GetTimeZoneOffset()"
PHP ::
PHP::
if (isset($_GET['TimeZoneOffSet']))
{
$ClientTime = $_GET['TimeZoneOffSet'];
$ServerTime = time();
$ServerTime = $ServerTime*1000;
$Diff = $ServerTime - $ClientTime;
echo $Diff;
echo " Server ";
echo $ServerTime;
echo " and client ";
echo $ClientTime;
}
网页在服务器上发布时间戳到php（使用get date函数），php应该采用时间戳并给出网页时间戳和当地时间戳之间的差异。
输出：
相差几乎不是70000微秒。即使服务器时区在PST中，客户端在EST中。这是正确的吗？
我如何实现这一目标？
Webpage Posts a timestamp to the php on the server (using get date function) and php should take the timestamp and give difference between the webpage timestamp and its local timestamp.
Output:
The difference is hardly 70000 microseconds. even though the server timezone is in PST and client is in EST. Is this correct?
How do i achieve this?
推荐答案
_GET [' TimeZoneOffSet']））
{
_GET['TimeZoneOffSet'])) {
ClientTime =
ClientTime =
_GET [' timezoneoffset的'];
_GET['TimeZoneOffSet'];
