GEORGIA, USA — For those of you wondering, it's not time to change those clocks back just yet.
Even though the sun is starting to set a bit earlier in Atlanta, the end of Daylight Saving Time is still a couple of months away.
Daylight Saving Time will officially end on Sunday, Nov. 3 at 2 a.m. Clocks will fall back to 1 a.m., losing an hour instead of gaining one.
The time it takes effect is technically 2 a.m., but what that means is if you pull out your phone (or glance at your watch) at 1:59 a.m. and stare long enough for the minute to change over, it'll go back right to 1 a.m. and start over again.
More on Daylight Saving Time
The practice has been implemented in some form since World War I when Germany originally introduced it to conserve power and energy by extending daylight hours.
The Standard Time Act of 1918 introduced daylight saving time to American clocks for the first time. What was then a temporary measure, which earned the nickname 'war time,' lasted from spring to fall in an attempt to cut energy costs during World War I. The act is also responsible for the five time zones still in place today.
The Department of Transportation was created and given regulatory power over time zones and daylight saving time in 1966. In order to correct confusing and alternating time zones, the Uniform Time Act of 1966 sought a nationwide standard for daylight saving time — from the last Sunday in April to the last Sunday in October.
Few changes have happened since then. Most recently, daylight saving time was extended by a few weeks in 2005 when former President George W. Bush changed the law. It is now observed from the second Sunday in March until the first Sunday in November.
Despite the national observance, Arizona and Hawaii don't observe daylight saving time. Under federal law, states are allowed to opt out of daylight saving time and remain on standard time but are not allowed to remain on daylight time.
