time was midnight exactly, as measured by solar or sun-dial time: that is, the sun may have been precisely in the nadir at that moment; but this difficulty would not arise in practice, as the law knows only mean time, not sun-dial time. If Greenwich time were made legal everywhere, and if electric clocks everywhere established communication with the master clock at the observatory, there might be another test supplied; but under the conditions stated, it would be a nice matter of _Tweedledum_ and _Tweedledee_ {127} to determine whether the house clock, the church clock, or a pocket watch, should be relied upon. All the pocket watches in the town might be brought into the witness-box, but without avail; for if some accorded with the house clock, others would surely be found to agree better with the church clock. This question of clocks, as compared with time measured by the sun, presents some very curious aspects in relation to longitude. What's o'clock in London will not tell you what's o'clock in Falmouth, unless you know the difference of longitude between the two places. The sun takes about twenty minutes to go from the zenith of the one to the zenith of the other. Local time, the time at any particular town, is measured from the moment of noon at that town; and noon itself is when the sun comes to the meridian of that place. Hence Falmouth noon is twenty minutes after London noon, Falmouth midnight twenty minutes after London midnight; and so on. When it is ten minutes after midnight, on the morning of Sunday, the 1st of January, in London, it is ten minutes before midnight, on Saturday, the 31st of December, at Falmouth. It is a Sabbath at the one place, a working-day at the other. That particular moment of absolute time is in the year 1865 at the one, and 1864 at the other. Therefore, we see, it might become a ticklish point in what year a man died, solely on account of this question of longitude, irrespective of any wrong-going or wrong-doing of clocks, or of any other doubtful points whatever. Sooner or later this question will have to be attended to. In all our chief towns, nearly all our towns indeed, the railway-station clocks mark Greenwich time, or, as it is called, "railway time;" the church clocks generally mark local time; and some commercial clocks, to serve all parties, mark both kinds of time on the same dial-face, by the aid of an additional index hand. Railway time is gradually beating local time; and the law will by-and-by have to settle which shall be used as the standard in determining the moment of important events. Some of the steamers plying between England and Ireland use Greenwich time in notifying the departures from the English port, and Dublin time in notifying those from the Irish port; a method singularly embarrassing to a traveller who is in the habit of relying on his own watch.
