Harper's School Geography: With Maps and Illustrations. American Book Company. 1885. стр. 129. „Standard meridians … They are 15° apart. The focal time on any one of them, therefore, differs exactly one hour from the local time on either of the two others between which it is situated. Each standard meridian is the middle line of a belt extending 15° wide.”
Committee on Standard Time (1884). What Shall be the Prime Meridian for the World?. International Institute for Preserving and Perfecting Weights and Measures. стр. 22. „It is intended that local time at any place on the surface of the globe shall generally be regulated by the standard meridian nearest or most convenient to such place in longitude.”
