  i may solve todays puzzle within the timelimit of 1 minute and can get good scores.according to your words ,the today's puzzle is put by the one who has scored the 20 points.Becoz,he has done it correctly within 1 minute.
  
  ALSO THERE ARE SOMETIMES SOME ERRORS IN THE TIME THE SITE DISPLAYS.
  I HAVE ALSO SEEN THE TIME OF ANSERING BEING GIVEN EARLIER THAN TIME AT WHICH THE QUESTION IS SUBMITTED.
  
  i think now you have understood the fact.
