start image swap javascript from fixed server time -


i'm setting simple mobile site charity , want show own ad banners local supporting businesses on bottom. i've got simple javascript swaps image banner every 10 seconds next in sequence:

window.onload = function () {     var rotator = document.getelementbyid("adbox");     var images = rotator.getelementsbytagname("img");     (var = 1; < images.length; i++)     {       images[i].style.display = "none";     }     var counter = 1;     setinterval(function ()     {        (var = 0; < images.length; i++)        {           images[i].style.display = "none";        }        images[counter].style.display = "block";        counter++;        if (counter == images.length)        {          counter = 0;        }     }, 7000); //1000 = 1 second };  <body ontouchstart="">     <div id="adbox">         <img src="_/ads/1.jpg" alt="one" width="320" height="70">         <img src="_/ads/2.jpg" alt="two" width="320" height="70">         <img src="_/ads/3.jpg" alt="three" width="320" height="70">     <div> </body> 

however resets , goes start of sequence when load different page. want start sequence @ fixed server time (say midnight) , cycle through, when load new page, don't go start of banners go 'ad server time'.

i think simplest , fairest way ads. did @ using iframe mean main site have sit in 1 , believe support of iframes on touch devices not great (which major issue this).

hmmm.

sounds don't need images 'rotate'.

how this:

 case(servertime)      if( 00.00 -> 04.00 )[ show ad #1 ]      if( 04.01 -> 08.00 )[ show ad #2 ]      if( 08.01 -> 12.00 )[ show ad #3 ]      if( 12.01 -> 14.00 )[ show ad #4 ] 

obviously above isn't valid code idea ?
