Ладно, не спорю, пример не удачный, так как писал не дома.
А вот так?

package 
{
	import flash.display.*;
	import flash.net.*;
 
	import mx.collections.ArrayCollection;
	import flash.external.ExternalInterface;
 
    public class Global
    {
		public static var original_img:Array;	
		public static var thumbImg_Arr:ArrayCollection = new ArrayCollection;
        public static var switcherThumbsLabel:String = "thumbnails";
        public static var time_start:*;
 
        public function Global():void
        {
 
        }// end function
		public static function Log(text_log:*):void {
			ExternalInterface.call("debugLog", "[" + time_start +"]" + text_log);
			//trace("["+ time_start +"]" + text_log);
		}
    }
}
