First we convert the clock time into position of hour and minute hands of 12 hour dial face. Then, we use the Flag Semaphore Character chart [1] to decode the hands.
9:00 => P
6:07 => E
10:45 => O
(the 4th clock)
7:45 => H
7:52 =>I
4:37 => N
The word would be PEOPHIN (which is a name of a pet species). Therefore, the 4th letter is P which is the same as the first one. The answer is 9:00.
Results: 1885 people guessed the correct answer earning themselves 1062 NP each.
