Then make the n input time spent in each title, the format HH: MM: SS, wherein, when (00 <= HH <10) HH represents, MM is minutes (00 <= MM <= 59 ), SS represents second (00 <= SS <= 59 ).

Export

The total time the output after n time summary, the format HH: MM: SS. After the summary, 00 <= HH <100
