So what about x = 100 degrees Celsius, y = 212 degrees Fahrenheit?
Two obviously different numbers. What should the difference be?
This is a suggestion, not a proof. The analogy between
Celsius-versus-Fahrenheit and TAI-versus-UTC is not at all
perfect. And we're dancing around between proofs from first
principles, versus demonstrations based on what makes the math
easier. But I'm afraid the "the numbers are different, so the
difference can't be zero" argument is not as compelling as you'd
