Standard time in the United States is a recent invention from 1883

Evidence

Our sense of time and our activities in time are coordinated through a grid of time zones, a grid so fixed in our consciousness that it seems to be the natural form of time, at least until we change back and forth between standard and daylight saving time. But standard time in the United States is a relatively recent invention. It was introduced on November 18, 1883. — James W. Carey, Communication as Culture- Essays on…, 843

Categorization

• QUESTION: Worth checking why daylight saving time disrupts the grid’s naturalized feel; the author gestures at it but doesn’t develop it.
• corroborated: 2 independent passages support this claim — James W. Carey, Communication as Culture- Essays on…, 843
