使い方
- Search and add the cities or timezones you care about.
- Use Live view to see synchronized clocks ticking in real time with each city's UTC offset.
- Use Compare view to lay cities side by side at a chosen reference time.
- Use Difference view to read the exact hour gap between any two cities, with daylight-saving offsets applied.
例
- Add New York (UTC-5) and Tokyo (UTC+9) and the difference view shows Tokyo is 14 hours ahead — 9:00 AM in New York is 11:00 PM the same day in Tokyo.
- The live view updates every second, so all selected cities stay in sync with the current moment.
