Is there still a valid reason to have timezones altering between states? is it just for agriculture? While we're, talking about changing time monitoring systems, can't we have 13 months with 28 days each? (and an extra day every 4 years added on to december?) :( Simple things, but that would allow us to follow the lunar cycle.
The counter to that is -- well, let's always stick with daylight savings time then. That has problems of its own. For example, sunset is a little after 4:00 PM in Boston in late December. If we stuck with daylight savings time, it'd be a little after 3:00. That would pose risks for school children walking home, etc.
Yes, I realize that people in Fairbanks Alaska have it much worse and daylight savings doesn't fix the problem for them, but there are a lot of people who live in the northern parts of the lower 48 that benefit from the time shift.
