Frequently Asked Questions (FAQ)
Which cities can I check the time for?
You can check the current time in supported cities including Seoul, Tokyo, New York, London, Paris, and Sydney. Search the list and add a city that is not already displayed.
Can I add a city that is not listed?
Only cities in the supported list can be added. The '+' search excludes the main city and cities already displayed, so each supported city appears at most once. Drag cards to reorder the cities you use most.
Is the time accurate? Could it differ from my computer clock?
The clock displays your device’s system time in the selected city’s time zone. If the time is incorrect, check your device’s date and time settings.
Are my settings saved?
When browser storage is available, your theme, added cities, city order, and display settings are saved for the next visit. The single large-clock view and its adjusted size are also restored in the same browser, but fullscreen and Keep screen awake must be requested again. The share button puts only the main city's fixed ID, digital/analog mode, 12/24-hour format, and regular-view font size in the link; it excludes the single-clock view, other cities, their order, and the theme.
Can I use it on mobile?
The layout adapts to PCs, tablets, and phones. Fullscreen support and behavior vary by browser. Check the digit size and orientation on your intended device before a class or presentation.
Can I use this clock for ticketing?
Use this clock to see your device time. It cannot guarantee the ticket platform’s opening time. The Server Time tool provides an HTTP-based estimate; also check the platform’s official announcement.
Does the clock work without internet?
After the initial load, time is calculated within your browser, so the clock works even without internet. However, some features like adding world cities require an internet connection.
Keeping a large clock on screen
Fullscreen alone does not prevent device sleep or screen lock. In single-clock or fullscreen view, select ‘Keep screen awake’ to request a Screen Wake Lock on supported browsers and check whether it is actually active. It is released in another tab and may be denied or released by device policy or battery state. Check device settings for long sessions and verify the time after returning from sleep or lock.
Comparing city times and dates
Check each city’s date as well as its time. Daylight saving time can change the offset. The fixed example table below may therefore differ from the current city clocks above.
