World Time Clock Master

World Time Clock Master is the easiest way to handle multiple time zones. This Chrome extension presents a unified clock face, real-time time conversions, and one-tap event scheduling so you can coordinate international calls and webinars without the guesswork.

From atomic accuracy backed by a vast timezone database (over 160,000 locations) to luxurious touches like real moon phases, sunrise/sunset, and haptic feedback, it turns global timekeeping into a premium experience. It also offers dynamic widgets for quick reference, and a clean list mode for scrolling through cities. A subscription unlocks unlimited time zones, more widgets, and automatic database updates.
