- Living Clock · Lantern Isle
- The sky, sun and moon follow your device’s 24-hour day. The promenade has 60 lanterns: one lights up each minute. A little ferry completes its harbor circuit every minute, showing the seconds. A quiet ripple marks the hour. Explore a day previews another time for 20 seconds. Sunrise, sunset and moon shape are artistic, not astronomical predictions.
- Keep screen awake
- Prevents the screen from automatically turning off while you are viewing this page. Useful as a desk clock. Press again to release it. Switching tabs or locking your device may release it, so check the enabled state when you return. Shown only in supported browsers.
- Fullscreen
- Hides menus and surrounding content so the clock fills your screen. Useful for presentations or viewing from a distance. Use Exit fullscreen or press Esc to return. Enable Keep screen awake separately if needed.
- Seconds · Milliseconds
- Show or hide seconds. Milliseconds adds three decimal places, down to 0.001 seconds. This adds display detail; it does not improve the accuracy of your device clock.
- 12h · 24h
- Switch between 12-hour time with AM/PM and 24-hour time from 00 to 23.
- Analog
- Shows a clock face with hour, minute and second hands below the digital time. Press again to hide it.
Keep the current device time in view while you work or present. Use Fullscreen for a large clock; choose seconds, milliseconds, 12/24-hour time or an analog face below. Choose a Living Clock scene, and keep your display settings in this browser.
About this clock
The display is calculated from your device clock on every update, so a delayed browser frame does not make it drift. It follows your device settings; if that clock is wrong, this display is too.
Display options
Read the digits as hours:minutes:seconds. For example, 14:07:09 means 2:07 PM and 9 seconds; this is a reading example, not the current time.
- Set Seconds to On to show the last two digits. Milliseconds adds three decimal digits without increasing the accuracy of the device clock.
- Choose 24h for hours from 00 to 23, or 12h for an AM/PM display. Analog adds hands below the digital clock.
- Use Fullscreen for a large display. Enable Keep awake separately if you want the screen to stay on, and check its state after returning to the tab.
If the displayed time looks wrong
Check the time-zone name and UTC offset below the clock before comparing it with another clock. This page follows your device’s local time zone.
- If the date or hour is wrong, check automatic date/time and time-zone settings on your device. A wrong time zone can shift the displayed hour even when the underlying clock is synchronized.
- If the seconds differ from a trusted reference, synchronize your device clock in its date/time settings. Refreshing this page or enabling milliseconds does not synchronize the device.
- For the current time in Korea while abroad, open World Clock and find Seoul. For an event on a ticketing site, open Ticket time and check the provider, sample age and uncertainty there.

Questions & Answers
Frequently Asked Questions
How do I display the current time with seconds?
Set Seconds to On in the display options below the clock. The digits read hours:minutes:seconds. Select 12h or 24h for your preferred format and Fullscreen for a larger display.
Why is this clock different from another clock?
Compare the time-zone name and UTC offset first. This clock uses your device time. Check the device’s automatic date/time and time-zone settings, then synchronize the device if its seconds are wrong. Refreshing this page does not synchronize the device clock.
Is this a server time or ticketing clock?
No. It displays your device time, not the time on a ticketing or registration server. Millisecond digits do not establish measurement accuracy.
How do I open the moving scenery?
Enable Living Clock, then choose Browse scenes. Use the day preview to explore the artwork; return to current time before reading the clock.
Why does the screen still turn off?
Wake lock can be refused or released by the browser, battery saver, or operating system. Check the toggle after returning to the tab.
Can I open every scene offline?
Not necessarily. Previously visited pages may be cached, but image scenes load separately and are not guaranteed to be available offline.
