<output>6</output>
6sec   So 6'o clock 5 *6= 
<gadget id="calculator">5 *6</gadget>
<output>30</output>
30sec   7'o clock 6 *6= 
<gadget id="calculator">6 *6</gadget>
<output>36</output>
36sec   .   .   .   10'o clock 9 *6= 
<gadget id="calculator">9 *6</gadget>
<output>54</output>
54sec   11'o clock 10*6= 
<gadget id="calculator">10*6</gadget>
<output>60</output>
60sec   12'o clock 11*6= 
<gadget id="calculator">11*6</gadget>
<output>66</output>
66sec   So, 66sec at 12'o clock.   ANSWER:66sec
