If your clocks are on Daylight Saving Time (DST), a.k.a. Summer Time, on the weekend when Standard Time resumes, make the time one hour earlier. A popular mnemonic device for remembering which direction to adjust is "spring forward; fall back". On some older clocks you have to advance the time 11 hours.
For example, in North America, every time zone of every country that observes DST except Cuba begins and ends DST at 2:00 AM. That means that on the 1st Sunday of Nov., or on the last Sunday of Oct. in most of Mexico, one minute after 1:59 AM is 1:00 AM. On the east coast of the U.S., one minute after 1:59 AM EDT is 1:00 AM EST, on the U.S. west coast, one minute after 1:59 AM PDT is 1:00 AM PST, and so on. In Europe, every country that observes Summer Time does the time changes at the same time (1 AM UTC), no matter which time zone they're in. So on the last Sunday of Oct., when universal time changes from 00:59 to 01:00, most of Europe changes from 02:59 CEST to 02:00 CET, eastern Europe changes from 03:59 EEST to 03:00 EET, and Western Europe changes from 01:59 WEST, BST or IEST (Irish Summer Time) to 01:00 WET or GMT.
There is currently only one place in world where the time change for DST is not one hour. On Australia's Lord Howe Island clocks are adjusted forward one half hour at the beginning of DST (on the first Sunday of October) and turned back one half hour at the end of DST (on the first Sunday of April). Because the Southern Hemisphere's summer is in the opposite half of the year from the northern hemisphere's summer, the southern hemisphere observes DST during the opposite half of the year from the northern hemisphere.
Daylight Saving Time is the name of the plan to set clocks ahead in spring and back in fall.
Clocks are set back one hour when Daylight Savings Time ends, typically in the fall. When the time changes from Daylight Saving Time to Standard Time, people usually "fall back" and set their clocks back one hour.
Standard time in 2010 began on March 14th, when clocks were set back one hour for daylight saving time. Time changed again on November 7th, when clocks were set back one hour to return to standard time.
Standard time begins on November 7th, 2021 in the United States. This is when clocks are set back by one hour, transitioning from daylight saving time to standard time.
Summer Time ended on Sunday 3 April @ 3 AM Local Summer Time and restarted on Sunday 2 October @ 2 AM Local Standard Time.
The standard for measuring time is set by the coordinated universal time (UTC), which is determined by atomic clocks at various observatories around the world. UTC is used as a reference to synchronize all other clocks, ensuring a universal standard for timekeeping.

No, they aren't. Clocks were already set up by the manufacturer.
Digital clocks will keep time at least as well as a manual mechanical clock.
Any atomic clock will automatically set the time.

On Sunday, November 7, 2010 at 2 a.m., Daylight Saving Time ends . What time is best is up to your discretion .
