We are using GMT + timezones. You are the one who opposed timezones and said you have a different approach. But yours is exactly like timezones. My question is that why should anyone switch to something "like" timezones when there are actual timezones?
It's not better because your offset time is much granuler and hard to calculate in your mind than timezones. And it doesn't offer anything new over timezones. Since you suggested it, you must see a benefit. What is it?
what the fuck do you think timezones currently do?
Are they just arbitrarily stuck to "maybe sometime close to local solar time"
It could literally be equally as granular as existing timezones. You could just remap timezones to the offsets directly, hell even less granular because who cares. Just delete the half hour offsets.
it's not adding anything new, that's not the point, in fact it's impossible to add something "new" to the concept of time, we've already defined it. It's an improved variant of timezones, where coordination is immediately more accessible, and less involved. It's explicitly less arbitrarily defined than the current timezones that we have no, because most of the time, you just wouldn't use them.
