Is possible to know the user time and date in php?

is possible to know the local time and date of the user who opens a php page? (not开发者_StackOverflow社区 server side time and date). If the answer is no, can show me an example of javascript combined with php? (im not a java developer) Thanks.

First, Java is not JavaScript…

And you could do this through hidden <input> in HTML.

<input id="user-time" name="user-time" type="hidden" />

and JavaScript function to associate with form on submit:

function submit() {
    document.getElementById("user-time").value = (new Date()).getTime();
}

After this, parse the timestamp in your server-side PHP.

Yes but it wouldn't be a 100% accurate. Using their IP you can determine what timezone they are in. See this question about doing just that.

Once you have their timezone you can use date_timezone_set to set the appropriate timezone in PHP and pull their date/time information.
