Thanks Vladimir 

It works but i have two more questions please  ,  why we multiply the date by 1000 and why i can't receive ticks before 2011.12.19

datetime -> milliseconds 

I twisted the crystal ball and it says: read the messages in the "Experts" tab

Please i searched in the "Experts" tab about my second question and i couldn't get answers , can you just answer me please or gvive me a link

Thanks again

I can’t read minds. I am not a telepath.
