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.

[remram]

Yeah the Line Islands are the exception as always.

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.

[remram]

Fine, they overlap with the UTC day. They are less than 100% compared to the UTC day, even if they can be 100% off with each other.
