Which timezones does this tool support?

It supports 18 commonly used timezones globally, covering major cities in Asia, Europe, Americas, and Oceania, including Beijing, Tokyo, London, New York, Sydney, etc.

Does it handle Daylight Saving Time automatically?

Yes. This tool uses the browser's built-in Intl.DateTimeFormat API, which automatically handles DST rules for each region without manual adjustment.

Is the world clock time accurate?

Yes. The world clock is calculated based on the local system time and timezone offsets, and auto-refreshes every second. Accuracy depends on whether your system clock is accurate.

Why might UTC offset be a decimal?

Some regions have timezone offsets that are not whole hours. For example, Indian Standard Time (IST) is UTC+5:30, and Nepal Time is UTC+5:45. This tool displays these offsets accurately.
