使用方法

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.

範例

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.
