You are taking a time tick using the 1400 signal from Buenos Aires, Argentina. You hear a 0.4 second dash followed by a series of dots, noting that the 29th and the 56th to 59th dots are omitted. At the start of the following 0.4 second dash (which is followed by an 8 second pulse), the comparing watch reads 02h 00m 15s. When compared to the chronometer, the comparing watch reads 02h 01m 29s, and the chronometer reads 01h 59m 50s. What is the chronometer error?
