Even worse. Daylight savings creators. I work in manufacturing and we literally stut down the production line for an hour during the "fall back" and "spring ahead" so we can manually change the time on every computer.
For quality control it did. The real concern is people messing up time. If there was a quality complaint we wanted it to be easy for people to go back thru production data. A lot of the people operating the machinery and performing quality checks at our facility are not well educated, and the need is there to make investigating quality tasks/entering quality data very easy.
