This dual-view approach makes it easy to toggle between a concise overview and a more detailed, interactive display.

A great strategy is to group your locations by project or team name so you can quickly spot each group’s local time. Label them in a way that makes sense to you — like “Team Paris” or “HQ New York” — and reorder your list so the most important clocks appear first. This way, you can glance at your device and immediately see who’s online and when. World Clock Master makes it easy to add or remove cities, so you can keep everything organized and up to date for each global team you manage.

Not exactly. While there isn’t one single “main” time zone, Coordinated Universal Time (UTC) is recognized as the global standard. All other time zones are defined in relation to UTC (for example, UTC+2 or UTC-5). This helps ensure consistency when converting between local times around the world.

Time zones split the world into regions where local clocks read the same hour. Each zone is set relative to Coordinated Universal Time (UTC), which acts as a global reference point. When you say “UTC+3,” it means the local time is three hours ahead of UTC. Countries often adjust their offsets for Daylight Savings Time, and some even tweak their time zones for political or geographic reasons. This system keeps sunrise and sunset roughly aligned with typical work and sleep schedules around the globe. Read our article about it!

World Clock Master fully supports time zones with unusual offsets (like UTC+5:30 or UTC+9:45). When you add a city in these regions, the app automatically displays the correct local time. You can schedule events or convert times just like any other zone — the app handles all the math in the background so you can stay focused on what matters.
