> Of course people would still publish those sorts of "conversion tables"/offsets, because people would still have that exact problem! But they'd possibly be a bit more precise than historically - with current computer tech, it might actually be more accurate, e.g. using actual GPS coords instead of broad swaths, so it would be like "Denver is 6.24 (or whatever) hours behind your current location." Let alone how much better that might work for cities in single-timezone China, say.
This is keeping (a rationalized version of) time zones in every respect except for how people set their clocks.
In the system you propose, people would operate at the equivalent of 9 AM to 5 PM, except you expect that they'd quote different times (even with fractional hours) to maintain the façade that time zones no longer exist. A business no longer operates nine to five, it's 1:15 PM to 9:15 PM, and people can't just say "Oh, Denver is six hours behind London right now" because Denver isn't exactly ninety degrees west of London.
Ironically, aside from everyone around the world setting their clocks to the same time, that's how time worked prior to the introduction of time zones, so I can't fault you for coming up with that idea.
