Question 1

Is the time accurate?

Accepted Answer

The clock is based on your device's system time and converts it in real-time according to each city's time zone. As long as your local time is accurate, the times for all cities will be accurate. Conversion is based on the browser's built-in time zone database, no internet connection required.

Question 2

Does it automatically handle daylight saving time?

Accepted Answer

Yes. For regions that observe daylight saving time, such as London, New York, and Sydney, the correct offset is automatically applied based on the current date; for regions that do not observe daylight saving time, like Beijing and Tokyo, a fixed offset is maintained without the need for manual adjustment.

Question 3

What does GMT+8 next to the time offset mean?

Accepted Answer

GMT±N indicates the current hourly offset of the city relative to Coordinated Universal Time (UTC/GMT), such as Beijing being GMT+8 and Mumbai, India being GMT+5:30. The offset changes with daylight saving time, and the tool displays the actual offset for the city at this moment.
