i think it auto conforms to your timezone on your pc when using gmdate but im not sure, I want a user to be able to select the choice but I gotta get it working first... can someone tell me by going to http://michael.hungerford.us/gmttimes.php and telling me what the time for (gmt) area is for you so i can check if it auto detects from your pc location?

on my pc my current time is (GMT + 01:00) so its just being wierd, im not sure why

what any of the date/time functions in php do is use the server time that the webpage is on. IE, if your server is your home computer, and the current time is 5:30pm on 12/8/06, then that will be the date PHP uses. There are a way around this, but you will need to have safe mode off to do it. I cannot remember exactly what it is but you could probably find it in the comments on the PHP.net website.

my error seems to be in the mktime, i erased it so it is

echo gmdate("l, F jS, Y \- h:i:s A"); echo " - (GMT) Casablanca, Dublin, Edinburgh, London, Lisbon, Monrovia"; echo " ";

and it appears ot display the correct time now...

gmdate shouldnt use server though since it uses gmt time conversion

Yea, you're right, it uses the gmt conversion from the server time. I misunderstood the original post, and simply glanced over the posted code. Sorry for the mishap.

Uh... what's wrong with that? It looks perfectly correct to me.

The other posters here are right: PHP is run on the server, not the client, so it uses the server's time.

gmdate should set it equivalent to gmt time though... I will use separate date and do like

$time = gmdate("h") + (value of something else...)
echo gmdate("l, F jS, Y \- "
echo $time;
echo ":i:s A";
