Frequently asked questions

Each city is converted with DateTimeZone for the same instant. The difference is the gap between those offsets on that date, including daylight saving.

The helper looks for hours when every selected city is between 09:00 and 17:00 local time. If no hour overlaps, it reports that no shared working hour exists that day.
