(KUTV) -- Daylight saving time is ending for Utahns and other states on Sunday, Nov. 4, at 2 a.m.

The annual turning back of the clock by one hour was once posed by Benjamin Franklin as a way to preserve candles that served as the main source of light in the 19th century.

However, it didn't actually get implemented until World War I with the Standard Time Act of 1918.

Other facts you may not know about daylight saving time are:

1. A Utah resolution has been proposed 15 times in the state legislature to ditch daylight saving time to match the Beehive State with the same time zone as Chicago and one hour ahead of Denver.

2. The U.S. Department of Transportation determines time zones and daylight saving time.

3. In World War II, President Franklin D. Roosevelt implemented a year-round daylight saving time that was commonly known as "War Time."

4. The transportation industry found the lack of nationwide consistency in time observance confusing enough to push for federal regulation. This drive resulted in the Uniform Time Act of 1966. The federal law was signed by President Lyndon Johnson.

5. Under Johnson's Act, states and territories can opt out of daylight saving. It isn't observed in Arizona, Hawaii, American Samoa, Guam, the Northern Mariana Islands, Puerto Rico and the Virgin Islands, according to the Congressional Research Service.

6. There is no s in daylight. The correct term is daylight "saving" - not savings - time. It's also supposed to be lowercase, not uppercase, according to the Associated Press stylebook.

7. The elderly - age 65 and up - may struggle with the time change more than their younger counterparts, USA Today reported.

8. While Utah and about 25 other states want to make daylight saving time changes, the U.S. Congress would have to approve any such law changes that want daylight saving year-round.

9. Four months of each year are in standard time, which basically means daylight saving time is not in use.

10. During the 1973 oil embargo by the Organization of the Petroleum Exporting Countries, in an effort to conserve fuel, Congress enacted a trial period of year-round daylight saving time from January 6, 1974, to April 27, 1975.

11. Although the "fall back" by one hour is an annual occurrence to reset clocks, it also serves as a reminder to change carbon monoxide and smoke detector batteries.
