It was 98 years ago today that the US Congress established time-zones and approved daylight savings time, two years after Germany and Austria-Hungary organized the first implementation, which began on April 30, 1916.

A good history of daylight savings time is over on Wikipedia. Interesting facts include it was first conceived by a New Zealander, used extensively during the world wars to conserve coal during daylight hours, and didn’t become common place until the 70’s as a result of the energy crisis.

And if you’d prefer to listen to a brief history, John Oliver did an interesting segment last year on Last Week Tonight.
