WASHINGTON — It's time to usher out daylight saving time across most of the United States and welcome back standard time.

At 2 a.m. local time Sunday, daylight saving time ended, and standard time returns for most people. It means an extra hour of sleep, perchance to dream, for one night.

Hawaii, American Samoa, Guam, Puerto Rico, the U.S. Virgin Islands and most of Arizona don't observe daylight saving time, so no need to change the clocks in those places.

Daylight saving time returns at 2 a.m. local time on Sunday, March 10, 2019.
