Questions and answers

Do the clocks account for daylight saving?

IANA zones follow date-specific daylight saving rules. Repeated times need a first/second choice; skipped local times are rejected.

Why do city dates differ?

Cities can have different dates because their time-zone offsets differ. Each clock shows the date in its own zone and uses the browser’s time-zone rules.
