Re: 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>

        <title>Untitled</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=yes&Month="+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> Tom At 10:38 AM 4/04/2002, Miguel Cruz wrote:

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?
