In autumn the daylight saving ends and the clock returns from summer time to standard time, also known as the winter time. The clock is turned back by an hour which allows to take advantage of daylight in the morning better.
In the USA, the time change has been applied since 1918. Many countries around the world change the time from summer to winter. In the case of the United States, the one hour shift takes place at 2 a.m. of local time. In the spring, the clock is moved from 01:59 a.m. to 03:00 a.m. DST. In autumn, the clock is moved from 01:59 a.m. to 1:00 a.m. DST. Since 2007, the end of the summer time takes place on the first Sunday in November, and the return to the summer time (by moving the clock forward) takes place on the second Sunday in March.
