Here is a function to convert unix/gmt/utc timestamp to required timezone.

function unix_to_local($timestamp, $timezone){
    // Create datetime object with desired timezone
    $local_timezone = new DateTimeZone($timezone);
    $date_time = new DateTime('now', $local_timezone);
    $offset = $date_time->format('P'); // + 05:00

    // Convert offset to number of hours
    $offset = explode(':', $offset);
    if($offset[1] == 00){ $offset2 = ''; }
    if($offset[1] == 30){ $offset2 = .5; }
    if($offset[1] == 45){ $offset2 = .75; }
    $hours = $offset[0].$offset2 + 0;

    // Convert hours to seconds
    $seconds = $hours * 3600;

    // Add/Subtract number of seconds from given unix/gmt/utc timestamp
    $result = floor( $timestamp + $seconds );

    return $result;
}
