The rate of angular change divided by angle sure as heck sounds like units of time to me. The absolute angle isn't, but the rate of change is, and UTC still tracks with rate of change, with a phase angle we periodically twiddle. That's like saying a watch or even an atomic clock doesn't measure time, it measures oscillations. It's being pedantic to the point of obtuse.
