Online Clock With Seconds
Three styles
Flip shows split cards that turn every minute, digital shows clean large numbers, and analog shows a classic dial with a second hand. Switch between 12 and 24 hours, show or hide seconds and the date.
Add a city to see its local time next to yours, handy for calls across time zones.
Made for a spare screen
Dark mode keeps the room calm at night and saves battery on OLED screens. The screen stays awake while the clock is open, so an old phone or tablet becomes a desk clock. Press F for fullscreen.
Where the time comes from
The clock shows your device time. If your device clock is set automatically, it matches network time to within a fraction of a second.
Questions
Is this the exact time?
It shows your device clock. Phones and computers that set time automatically are usually accurate to well under a second.
Can I keep the screen from turning off?
Yes. While the clock is open, TimerHome asks the browser to keep the screen awake.
Can I show another city?
Yes. Add a city and its local time appears under the main clock.
