       dLocal.setUTCFullYear(1970);
       dLocal.setUTCMonth(0);
       dLocal.setUTCDate(1);
       dLocal.setUTCHours(0);
       dLocal.setUTCMinutes(0);
       dLocal.setUTCSeconds(0);
       dLocal.setUTCMilliseconds(0);
       
       //using the UTC() method, you could write the same thing in this way:
       
       var nUTCDate:Number = Date.UTC(1970, 0, 1);
       var dLocal:Date = new Date(nUTCDate);
   }
 }

}

       </source>
   
  

using the Date class"s static parse() method.

   <source lang="java">

package{

 import flash.display.Sprite;
 
 public class Main extends Sprite{
   public function Main(){

UTC() is a method that returns the time value in milliseconds from midnight on January 1, 1970

   <source lang="java">

package{

 import flash.display.Sprite;
 
 public class Main extends Sprite{
   public function Main(){
      // The UTC() method takes the same arguments as the Date constructor: year, month, date, hour, minutes, seconds, milliseconds. 
       var nUTCDate:Number = Date.UTC(1970, 0, 1, 0, 0, 0);
       
       var nUTCDate:Number = Date.UTC(1970, 0, 1);
