On 1st July at 8 a.m. by my watch, it was 4 minutes past 8 a.m. by my clock. I went to Greenwich and, when my watch said noon, the true GMT was 5 minutes past noon. That evening, when my watch said 6 o'clock, the clock said one minute to 6 p.m.

On 30th July, at 9 a.m. by my watch, it was 3 minutes to 9 by my clock. At Greenwich, when my watch said 10 minutes past noon, the true GMT was 5 minutes past 12. That evening, when my watch said 7 p.m., the clock said 2 minutes to 7 p.m.

My watch is only wound up for each journey and goes uniformly during any one day; the clock is always going, and goes uniformly. How am I to know when it is true noon on 31st July?
