    Hello

    At sign-up, I collect the user's country and set the nearest timezone (they can change this if it is incorrect).

    I want to display time local to a user. How can this be done?


    Thanks

    this is how I personally do it. it just gives you a brief on the calculations, you can do it your own way

    $t_ime = the timestamp ( time() ) stored in the db
    so if you want just the current time then $t_ime = time();

    $this->tzone
    is a number I believe
    since times are set at GMT0

    for example
    GMT+1, tzone would be 1
    or GMT-10, tzone would be -10

    and eh, I'm not too sure what else to say really. I wrote this three years ago when I was 15... but it's always worked for me


    edit

    
//set this to whatever timezone the user is in. for example -10, 11, -3 ect..
$Tz = -10;

//set timezone
date_default_timezone_set('Europe/London');

//Current server time
$Current = time();

//Work out
$add = ($Tz * 3600);

//Work out timezone
$Current = $Current + $add;

//show local time
$result = date('M d, Y H:i', $Current);
    Code (markup):

    You have to use javascript or actually ask the user what their timezone is. There is no server side method of determining this, as the user's browser does not pass this information in a page request.

    You can also use a geoip database to get closer, but it's not exact.
