What does "3:00 PM" mean? Serious question. If the government is shifting work hours at different times of the year, then "3:00 PM" will mean different things. It will be before school lets out sometimes, and after school lets out during other months. It'll be 2 hours before work ends, or only one hour.
I'm no fan of DST, I think we should pick a timezone and stick with it. My argument is that DST is better than having a massively coordinated change in work schedules, because that's even more complicated than just moving the hour hand twice a year.
"Massively coordinated" is just every news anchor being obligated to say "Remember today the work day starts at 9:00PM and ends at 7:00PM" (with casual reminders weeks before of course), that's it, has anybody even tried to see if that brings chaos or if is just a baseless myth?
Not all work shifts start and end at the same time, nor are they the same length. Some people work 5 days a week, 8 hours a day, others do 4/10s. Bus drivers have to be working when others are commuting.
