But it overlaps. It's off, but less than 100% off.
"2021-Q1" can be a completely different and non-overlapping range between regions, and even between companies in the same region.

2021-10-24 in UTC+14 (Line Islands) and UTC-10 (Hawaii) are, in fact, 100% off.

We could've gone with most of New Zealand (UTC+13 summer time) and any of the US territories in UTC-11. These are marginal cases, not exceptional ones.
That makes doesn't make it a bad time interchange format for certain use cases, though. Just like everything else with time, one must be aware of caveats. Those include timezones, leap periods, culture, DST, formats, legislation (modern and ancient), etc.
