A certain hall contains two cuckoo clocks

A certain hall contains two cuckoo clocks. If the first clock chirps 20 times per hour and the second clock chirps 9 times per hour, and both clocks chirp for the first time at 2:03 pm, at what time will the first clock have chirped three times as many times as the second clock can chirp per hour?

This problem repeats another one in the library (at most with different numbers), so it's left out of browsing.
