Events CountDown Timer Script

have Events CountDown Timer jquery script?
i use this:
<font color="#ff6600">Devil Square:</font>
<font color='#DDA943'>
<span id=timespan>
<script>
var dods;
<?
echo "var minute = ".date("i").";";
echo "var secundes = ".date("s").";";
?>
//document.write(55-minute);
dsin = minute * 60 + secundes;
function changeeventtime()
{
dsin = dsin + 1;
dods = 55*60 - dsin;
min = Math.floor(dods/60);
sec = dods%60;
if(dods < 0)
{
document.getElementById("timespan").innerHTML="Open";
}
else
{
if(min < 10) min = "0"+min;
if(sec < 10) sec = "0"+sec;
document.getElementById("timespan").innerHTML=min+":"+sec;
}
window.setTimeout("changeeventtime()",1000);
}
changeeventtime();
</script>
</span>
</font>

but my EVENT TIME for DEVIL SQUARE is:
0 30
3 30
6 30
9 30
12 30
15 30
18 30
21 30
and my script show every hour.
have other script or how to modify this with my config

Oh this is fun....
The reason your code is only counting down by the hour is because the counter is being set by:

[dods=55*60-dsin] (this is making the "counter" start from ~approx(55 mins) in seconds of course.

The simplest way I can think of fixing it is to [since you seem to use JS more then PHP] is to use a few [IFs] make ranges between your start times and current time and then set the {55*60} part of your code to the difference between the two times.....

If that made no sense then here is a cut throat explanation:

[Time Event starts]-[Current Time]=[Time Left] You will probably need 3 or 4 [IFs] I figure...

Or you can go full PHP and do a [SWITCH] with case expressions and that will save you a few lines..

Let me know if this helps ya.:ehh:


Oh a bit rude of me.... If you show some effort in figuring it out. I will help you rewrite it...


------------------------SD now and ALWAYS---------------------

PHP Code:

---

<span id=dstime>
                <script type="text/javascript">
                    var    ds;
                    var    acum    =    new Date();
                    var    minutes    =    acum.getMinutes();
                    var    seconds    =    acum.getSeconds();
                    dsstart            =    minutes * 60 + seconds;
                    if    (minutes    >    30)    doin    =    3600 - dsstart;
                    else    doin    =    -dsstart;
                    ds    =    doin + 25*60;
                    function    bceventtime()
                    {
                        ds    =    ds - 1;
                        if    (ds    <    -5*60)
                        {
                            ds    =    3600 + 30*60;
                            ds    =    ds-1;
                        }
                        min    =    Math.floor(ds/60);
                        sec    =    ds%60;
                        if    (min    <    0)
                        {
                            document.getElementById("dstime").innerHTML    =    "Open";
                        }
                        else
                        {
                            if    (min    <    10)    min    =    "0"+min;
                            if    (sec    <    10)    sec    =    "0"+sec;
                            document.getElementById("dstime").innerHTML    =    min+":"+sec;
                        }
                        window.setTimeout("dseventtime()",1000);
                    }
                    dseventtime();
                </script>
</span>

This is my default code for Devil Square, this code was for 00 time but my DS is at 30 minutes, and in line ds i put this "doin + 25*60;" for event start at 30 minutes, this work for minutes, but for hours i try to change line: dsstart = minutes * 60 + seconds; to dsstart = minutes * 180 + seconds; for every 3 hours but this not work:( show other time.
