Daylight saving time in the U.S. ends at 2 a.m. Nov. 5, when clocks should be turned back one hour as standard time resumes.

The time change may result in questions for payroll departments about overtime pay rights under the Fair Labor Standards Act. Employers should observe federal rules for late-shift employees scheduled for early morning work.

Employees working an early morning shift would be on the job an extra hour after clocks are set back. The extra hour may result in unplanned overtime for workers covered by the FLSA. Compensation is required under the law for covered employees who work the extra hour.

Arizona, Hawaii, Puerto Rico, the U.S. Virgin Islands, and American Samoa do not observe DST.

In 2018, daylight saving time starts March 11 and ends Nov. 4.
