Amid nippy autumn air and a gathering of Halloween ghosts and goblins, most of the nation is setting clocks back an hour with the return of standard time.
The clocks changed officially at 2 a.m. Sunday, but most people will have done it before going to bed Saturday night. That shifts an hour of light from evening to morning as trick-or-treaters make their rounds Sunday night.
Daylight-saving time returns the first Sunday in April 2005.
The change does not affect Arizona, Hawaii or the portions of Indiana in the Eastern time zone, which do not observe daylight time.
