There is no adequate rationale for following Daylight Savings Time in the United States.
The biannual time change is counterproductive for our personal lives and provides unnecessary disruption of economic activity. Moreover, daylight savings time has negative consequences for our health.
We ask the White House to cease the switch to Daylight Savings Time in 2015 and subsequent years. As multiple states do not follow DST, a switch of federal operations to universal standard time will promptly be followed by states which are expected to follow suit.
