I know yet another question this kind.Sorry ..
But I'm not JS dev and have one time task.

Issue is that I have one value that is returned by $(this).attr("ows_Modified"); (Sharepoint and SPService thing)
This value seems to be string 'Fri Oct 19 2012 13:35:45 GMT+0200' need to compare it to the date object with value format like this: 2012-10-29 12:14:13 and check with one is newer.
Any ideas how to do this please ?
