About World Clock
World Clock shows the current time in twelve major time zones side by side — UTC, Beijing, Tokyo, New York, Los Angeles, London, Paris, Berlin, Moscow, Dubai, Mumbai and Sydney. Run it and you get a single list of zone names paired with the local time in each, turning the awkward question of what time it is somewhere else into one glance.
The times are read through the browser's internationalisation support, so they reflect real daylight-saving rules rather than fixed offsets. New York and London, for instance, show a shifting gap through the year as each zone moves its clocks on its own schedule, and the tool reports whatever the correct local time is at the moment you run it.
Two expectations are worth setting. The clock is a snapshot, not a live display — it does not tick, so run it again for a fresh reading. And it reports hours and minutes only, without seconds, which is ample for scheduling a call but not for timing something precise.
How to use World Clock
- 1 There is nothing to enter — World Clock reads the current time itself.
- 2 Read the list of zone names and the current local time shown against each.
- 3 Run it again whenever you want the times brought up to date.
Frequently asked questions
Is this a live ticking clock?
No. It reads the time once when you run it and prints the results. There is no automatic refresh, so re-run it for an updated list if time has passed.
Which zones are covered?
Twelve: UTC, Beijing, Tokyo, New York, Los Angeles, London, Paris, Berlin, Moscow, Dubai, Mumbai and Sydney. It is a fixed list aimed at common business hubs rather than every zone in the world.
Does it account for daylight saving?
Yes. The times come from the browser's time zone data, so they follow each region's actual DST rules and shift automatically when a zone changes its clocks.
Why are seconds not shown?
The output gives hours and minutes, which is what you need for planning a call or a meeting. Seconds would change between runs and add noise rather than usefulness.

How World Clock behaves in detail
These are the specifics of this implementation — the exact ranges, defaults and fixed settings you are working with.
| Parameter | Value |
|---|---|
| Inputs | none — the form has no fields, so there is nothing to fill in |
| Zones listed | 12 fixed IANA zones, the same list used by the Time Zone Converter |
| Format | Intl.DateTimeFormat as en-US with hour12 off, hour and minute only |
| Output shape | one line per zone, prefixed with the raw zone identifier such as America/New_York |
| Timing | every zone is read once, at the moment the output is produced |

What World Clock does not do
Knowing the edges of a tool saves more time than another list of its features. These are the cases where it will not do what you might expect.
- It is a one-off snapshot. Nothing on the page ticks and no timer is set, so the times stop being true as soon as they are printed, there is no seconds column to show how stale the reading is, and the button has to be pressed again to refresh.
- Twelve fixed entries, keyed by time-zone identifier rather than by city or country. There is no search box, no way to add a city and no local offset figure, so countries that span several zones — the United States, Russia, Australia — are each represented by a single city.
- Neither the date nor the UTC offset is shown. A reading taken just after local midnight can therefore look identical to one taken just before it, since only hours and minutes appear, and no line indicates whether that zone is currently on daylight saving.
