This argument makes less and less sense with each passing year. I'm old enough to remember when we had to change all the clocks by hand, and some people had no idea how to change the clocks in microwaves and VCRs or their car, so it'd be off by an hour for half the year. Somehow we managed fine.

These days all clocks change automatically, and there are standard and constantly improving datetime libraries to help applications manage these human factors in a standard way. Your morning alarm is automatically updated, you calendar events automatically reflect the timezone they are defined in.

The only curveball is when when the government arbitrarily changes the rules, like then did not too long ago in extending DST. And which DST advocates are advocating for doing _again_.
