Fortunately, that's often the case. GMT can be ignored, and the other
three differ by less seconds than most humans ever care about. If
you're scheduling a meeting, for instance, nobody's going to care if
your clocks differ by 36 seconds, which is as much as TAI and UTC will
differ in a few hours (there's a leap second scheduled for midnight at
the end of June 30th this year, and as my clock is now showing July,
it'll be happening soon). The difference between UTC and UT1 is
insignificant to virtually all humans, given that it's never more than
a single second; it's only high-precision calculations that ever need
concern themselves with that. So, yep! I share your gladness.
Distinctions exist but most of us don't have to worry about them.
