Calculate time (world)

[Yizi]

Hi, this is my first post and I just need some guidance, I'm trying to write a function (ultimatly create a page) where it would show where in the world is 12 clock e.g. so I'm base din UK and I visit the page (run the function) and it would scan all time options possible and spits out where (if) in the world it's 12 lock. 

 

Thanks.

Have an array containing each time zone. Loop through it creating DateTime objects and testing if they have a 12 hour hand. Once you've found the timezone break out and display the zone.

 

Using http://us3.php.net/manual/en/datetimezone.getlocation.php you an get a friendlier name as well.

To get you started, this will get the array of timezones

$tz_array = DateTimeZone::listIdentifiers(DateTimeZone::ALL);
