The bill would eliminate Daylight Time and redefine Eastern Standard Time etc. to be the same offset they currently are during daylight time.

Given that the US Congress doesn't really have the social authority to do the latter...

I think you're wrong. They really are re-defining e.g. EST to be the current DST but without yearly DST change.

How would this work? Parts of Canada, parts of Mexico, Panama, Colombia, mainland Ecuador, Peru, parts of Brazil, and a bunch of islands are all on Eastern Time. Even if the US changed their own definition of EST it wouldn't change other countries' observations of EST.

Shhh... The Narrative has now been decided, and going against it on HN is racist or something.

A comment above states exactly the opposite.
