So why not keep time as a constant and if individual places want to change times they can do that
Even just single states can have vastly different sunrise and sunset times and changing 300m people’s schedules so that a few people can have a few extra minutes of sun in the morning for part of the year seems absolutely ridiculous
A local school district could very easily do a 1 hour shift as the sunrise gets later so that it properly aligns with their local school pickup times
