The Timer displayed is 1 hr (HH:MM:SS) in decrement order. I have to display a pop out when 50 mints complete after that remaining 10 mints one pop up should display saying 10 mints with 0 sec.

After that for every 2 mintues the pop up appear showing 2minutes left remaining time out.

Example: It was showing 8 mintues left for time out, but the pop should appear with 8 minutes left.
