I don’t know about other people, but I want even aware that they labeled them differently until a few years back. We I’m in EST and we still just call it that in conversion, whether it’s savings time or not (savings runs here is EDT).

I’m not so sure about that. I’m no lawyer, but I do know that there’s a lot of legal precedent for allowing people/things to operate a certain way, like land use. However, technology is still new to the legal system that’s set in the 1800s.
