[PHP] Managing time zones
Among other user preferences, I need to record their time zone, so that timestamps retrieved from a database can be displayed in their local time. There are all sorts of schemes for this, providing varying levels of detail (for a lot of detail, have a look in /usr/share/zoneinfo!). I would probably be willing to sacrifice subtle city-by-city idiosyncracies in exchange for simplicity as long as I were still able to handle daylight savings time for major populated areas. Recording +0400, for instance, is not good enough. Has anyone worked with this in the context of PHP? Any good pointers or inspiration?

Re: [PHP] Managing time zones
Hi
One method is to use javascript to get the clients date/time then create a
diff between that and your time and use it to change the display times.
Here is a demo of getting the remote date and time
pre
html
head
titleUntitled/title
?if(!isset($Submit)):?
script language=JavaScript
!-- begin
function gogo() {
var dt = new Date();
var mm,dd,yy,h,m,s;
mm = dt.getMonth()+1;
dd = dt.getDate();
yy = dt.getYear();
h = dt.getHours();
m = dt.getMinutes();
s = dt.getSeconds();
document.location=?echo
$PHP_SELF??Time=+h+:+m+:+s+Submit=yesMonth=+mm+Day=+dd+Year=+yy
}
// end --
/script
?endif?
/head
body?if(!isset($Submit)):? onload=gogo()?endif?
?
if(isset($Submit)):
echo Remote date = $Month/$Day/$Year $Time br;
endif;
?
/body
/html
/pre
