世界の主要都市の現在時刻。
Track live time across multiple cities on one screen. The clocks update every second from your browser's clock, adjusted against the IANA timezone database, so daylight saving transitions are handled automatically on the correct dates for each zone.
Add any of 33,000 cities to your dashboard. Your selection persists in local storage, so the same set of cities loads on every visit. Day and night indicators show whether each city is currently in daylight, and the working-hours overlay highlights when business hours overlap across the zones you follow, useful for scheduling meetings with remote teammates.
