Abstract
Standard Times throughout the World—A useful brochure, with this title, published by the U.S. Bureau of Standards, contains maps and tables which give the differences between the times used at various stations and those of Greenwich and Washington. The maps bring out the fact that the boundaries of the successive hourly time zones are far from conforming with the theoretical meridians; in fact they are made to conform with the boundaries of States or countries. One might expect that the 180° meridian where the day changes, which is nearly all water, would be straight; but even this shows notable deflections. These irregularities emphasise the utility of such a publication as the present one; without it one might frequently make errors of an hour.
