That’s not exactly what I’m saying. People generally don’t like switching between daylight and standard times. Any state could switch to standard time today, but they don’t because retailers want more sales hours. Instead they’re pushing for a change to allow more sales hours year round.

The idea is that businesses like the extra hour because people don’t shop as much after dark.

It served the plot in episode 1 of Game of Thrones, but it certainly wasn’t tasteful.
