Daylight Saving Time.
The federal government first officially recognized standard time during World War I, in an act to establish Daylight Saving Time. Posters proclaimed that advancing the time in each zone to give an extra hour of evening daylight would lead to victory. At war's end, Congress repealed the daylight saving provision of the act in response to farmers more in synch with the sun than the clock. During World War II, Congress authorized a temporary year-round daylight saving time, dubbed "War Time." While states and localities haphazardly observed Daylight Saving Time after 1945, no national legislation provided for it until the Uniform Time Act of 1966. Arizona, Hawaii, parts of Indiana, Puerto Rico, the US Virgin Islands, and American Samoa do not observe Daylight Saving Time. |
