Daylight savings time starts at 2 a.m. Sunday, March 11, when clocks are set forward one hour. Shift workers on duty at that time who work one hour less and who are paid for a full shift may raise questions under the Fair Labor Standards Act. An additional hour of pay provided to an employee who works less than a "full" shift need not be included in calculating the worker's regular rate of pay when considering any overtime for that week. At the same time, the extra hour of pay may not be credited toward any overtime pay that may be due. When daylight savings time ends, Employees working a nine-hour shift because the clock is turned back must be paid for all hours worked, and the extra hour must be counted in establishing the hours worked in that week.
