Hi everyone....I have a problem on my php date function... and i hope someone will help.... the PHP date function outputs incorrect results... It outputted incorrect date which is 8 hours late.... and i found out that the timezone has been set to UTC. So ive search the net and found out that you can set the timezone by explicitly adding a code date_default_timezone_set('Asia/Manila'); for example coz. im from the Philippines. So i tried the code and it works fine, but when i set date.timezone = Asia/Manila in the php.ini file. It doesnt work... I hope i can find answer here coz. these has been my problem for a long time... any response would be greatly appreciated tnxs :'(

try to use php function to set the correct zone.


if the php.ini settings does not make any change, try to ask the host's support. if you host your own website, try to restart the server.

Edited by djjjozsi: n/a


date.timezone = "America/New_York"
date.timezone = America/New_York


i tried restarting the server it doesnt work, i tried quoting the value of time zone ex. date.timezone = "America/New_York" still it doesnt work... please help.


weeeee! yes at last i found problem.... the problem was with my old wampserver2.0e. Its php.ini wont work... so i downloaded the latest version wampserver2.0i and i configure the timezone and it work perfectly. I dont know why wampserver2.0e php.ini doesnt work. thanks to all the people who responed and give their ideas on my problem... tnxs, it means a lot to me.


This may solve your problem..

if(isset($_POST['tz'])) {
    // store the selected value for future use in DateTimeZone
    $_SESSION['tz'] = $_POST['tz'];

    // timestamp to convert (just an example)
    $currentdatetime=date("Y-m-d h:i:s A");
    $timestamp =strtotime($currentdatetime); //1240349566;
    // set this to the time zone provided by the user
    $tz = $_SESSION['tz'];

    // create the DateTimeZone object for later
    $dtzone = new DateTimeZone($tz);
    // first convert the timestamp into a string representing the local time
    $time = date('r', $timestamp);
    // now create the DateTime object for this time
    $dtime = new DateTime($time);
    // convert this to the user's timezone using the DateTimeZone object
    // print the time using your preferred format
    $time = $dtime->format('g:i A m/d/y');

    print $time;

// create an array listing the time zones
