Using JQuery to Filter SharePoint List Items by Modified Field

After experiencing a very hard time browsing the internet for answers on how to retrieve items from a SharePoint list using the Modified or Created field as a filter for getting items created or modified on the current day , I then came up with the following implementation in javascript/jquery:

If you are using REST API the datetime literal is used as, e.g. datetime'2013-03-12T12:01:38Z' (This is ISO format) or datetime'2013-03-12′. Therefore, I needed the date in the format yyyy-mm-dd.

Here is the Code for filtering the list:

var d = new Date();
var date = convertToDate(d);
//querypath to be used as url when making an ajax call
var querypath = "http://farmname.com/site/_vti_bin/listdata.svc/listName?$filter=Modified gt datetime'"+date+"'";
$.ajax({
 url:querypath,
type: "GET",
dataType: "json",
headers: {
Accept: "application/json;odata=verbose"
}
});
function convertToDate(date)
{
   var mnth = date.getMonth() + 1;
   var day = "";
   //appending 0 for day less than 10 days since getDate() will for instance return 02 or 03 as just 2 or 3

   if(date.getDate()<10)
   {
      day = "0"+date.getDate().toString();
   }
   else day = date.getDate().toString();

   return date.getFullYear() + "-" + mnth + "-" + day;
}

I hope this will help many who face this kind of challenge!
