World Clock

See the current local time in ten major cities around the world at a glance, updating live every second.

Before mechanical clocks were synchronized across distances, "what time is it" was a genuinely local question — every town set its own clock by the sun directly overhead at noon, which meant two cities a hundred miles apart could disagree by several minutes and nobody cared, because nobody needed to coordinate anything between them. That stopped being tenable once railroads connected cities on fixed schedules; a train timetable is meaningless if every stop along the way is keeping its own version of noon. Standardized time zones were essentially invented to solve a scheduling problem, not an astronomical one, and that's still exactly what a world clock is for today.

The modern version of that same problem is coordinating with people, not trains — a colleague in Tokyo, a supplier in London, a family member who moved to Sydney. A world clock's entire job is answering "what time is it there right now" instantly, for as many places as you need to track, without you doing time-zone arithmetic in your head every time.

This version starts with a handful of commonly checked cities, but the real point is the search: type any city or region name and add it to your own personal list, which is then remembered in your browser for next time. That flexibility matters because everyone's "there" is different — the fixed list on most world clock tools is a guess at what's popular, while this one is built around whatever specific places actually matter to you.
