HISTORY71 - Time Zones and Daylight Savings Time

Image
Recently, most people in United States moved their clocks an hour forward, observing Daylight Savings Time (DST).  I live in Arizona, which does not observe DST (even though my “smart a_ _” bedside clock moved the time one hour forward anyway).  While resetting that clock, I decided that the history of time zones and DST would be a good topic for a blog.     After a short introduction, I will cover the need for standard time, America’s first time zones, the idea of DST, U.S. Congressional actions defining time zones and DST observance, U.S. time zones today, DST controversies, and will finish with worldwide time zones and DST observance. My principal resources include “Time Zone,” “Daylight Savings Time,” and “International Date Line,” Wikipedia.com; “A Brief History of Time Zones,” geojango.com; “History of Time Zones,” bts.gov; “Daylight Savings Time,” crsreports.congress.gov; “U.S. Time Zones in 1918,” papershake.blogspot.com; “The History of and Use of Time Zones,” thought.co
