Doc: fix bogus example about ambiguous timestamps.

I had a brain fade in commit d32899157, and used 2:30AM as the
example timestamp for both spring-forward and fall-back cases.
But it's not actually ambiguous at all in the fall-back case,
because that transition is from 2AM to 1AM under USA rules.
Fix the example to use 1:30AM, which *is* ambiguous.

Noted while answering a question from Aleksander Alekseev.
Back-patch to all supported branches.
