Communication about times would get so much easier, communication about schedules would get so much easier.
Except that it wouldn’t. It would make communication about time a culture sensitive topic. Sure, the exact time of day in relation to the position of the sun might get lost with our current system, but if someone tells you “I’ve slept til 12am” at least you know it was somewhat around noon. Under your new system you’d always have to consider where someone lives.
Ahem. Oops.
But in a way that’s a good example for what I meant. You and me communicate time both in reference to the time of day, not a virtual time of the planet that means something else to everyone depending on location, and you easily could spot my mistake.
So let’s just say I did that on purpose.
Is being able to communicate about stuff like that casually, where you do not mean a specific time anyway, really worth the giant pile of pain that time zones add to actual scheduling?
