Time may be compared to a great stream forever flowing onward. To us, nature, in its widest amplitude, is a unity. We have but one earth, but one universe, whatever its myriad component parts. That there is also but one flow of time is consistent with the plain dictates of our understanding. That there can be more than one passage of time is inconceivable.
From every consideration, it is evident that the day has arrived when our method of time-reckoning should be reformed. The conditions of modern civilization demand that a comprehensive system should be established, embodying the principle that time is one abstract conception, and that all definite portions of it should be based on, or be related to, one unit measure.
On these grounds I feel justified in respectfully asking the consideration of the Conference to the series of recommendations which I venture to submit.
The matter is undoubtedly one in which every civilized nation is interested. Indeed, it may be said that, more or less, every human being is concerned in it. The problem is of universal importance, and its solution can alone be found in the general adoption of a system grounded on principles recognized as incontrovertible.
Such principles are embodied in the recommendations which I am permitted to place before the Conference. They involve, as an essential requirement, the determination of a unit of measurement, and it is obvious that such a unit must have its origin in the motion of the heavenly bodies. No motion is more uniform than the motion of the earth on its axis. This diurnal revolution admits of the most delicate measurement, and, in all respects, is the most available for a unit measure. It furnishes a division of time definite and precise, and one which, without difficulty, can be made plain and manifest.
A revolution of the earth, denoted by the mean solar passage at the Prime or Anti-prime Meridian, will be recognizable by the whole world as a period of time common to all. By general agreement this period may be regarded as the common unit by which time may be everywhere measured for every purpose in science, in commerce, and in every-day life.
The scheme set forth in the recommendations has in view three principal objects, viz:
1. To define and establish an universal day for securing chronological accuracy in dates common to the whole world.
2. To obtain a system of universal time on a basis acceptable to all nations, by which, everywhere, at the same time, the same instant may be observed.
3. To establish a sound and rational system of reckoning time which may eventually be adopted for civil purposes everywhere, and thus secure uniformity and accuracy throughout the globe.
