Beginning of the Long Dash
In the early days of formal timekeeping, determining the time was a specialized branch of astronomy. Now it is a branch of physics. Through decades of innovation, scientists at the Dominion Observatory and the National Research Council have created a Canadian time signal based not on the stars but on the cesium atom. This history of some 125 years of timekeeping in Canada documents a resolution in...
