USA: Suggested by FDR, Congress imposes Daylight Saving Time, also called War Time, in an effort to conserve fuel by reducing the need to use artificial lighting. It will remain in effect year-round until 30 Sep 45.
The practice of Daylight Savings Time has been both praised and criticized. Adding daylight to evenings may benefit retailing, sports and other activities that exploit sunlight after working hours, but can cause problems for evening entertainment and other occupations tied to the sun.
Scene from the 1924 Harold Lloyd Jr silent film classic "Safety Last" which really has nothing to do with the implementation of Daylight Savings Time during WWII, but it is comical and representative of time.
When told the reason for daylight savings time the Old Indian said,
"Only the government would believe that you could cut a foot off the top of a blanket, sew it to the bottom and have a longer blanket."
