Comparing datetimes and timezone issue

skylabel asked
Last Modified: 2009-07-29
I have the following code to retrieve a date and compare with the present time, which works, but what if I want to say as long as it's still today, count it as the future, even though the time might have past already.

Also, I'm not too sure how to handle time zones with this, as $commenceDate, which is stored in MySQL database  and refers to a GMT +8 timezone. I'm using PHP 4.3.

$commenceDateTime = $row['commenceDateTime']; //read from MySQL datetime field
$commenceDateTime = strtotime( $commenceDateTime );

$currentDateTime = mktime();

if ($currentDateTime >= $commenceDateTime) {
   echo "past";

else {
   echo "future";
