Frequently Asked Questions

What is a digital clock with seconds online?

A digital clock with seconds online shows the time as numerals — hours, minutes, and seconds — in your browser, updating every second in real time. This one uses a seven-segment LCD typeface for the look of a classic digital alarm clock, with the seconds highlighted in your accent color and, in 12-hour mode, the AM/PM indicator on its own line below.

Can I use this as a full screen digital clock display?

Yes. Click the fullscreen icon in the controls cluster at the bottom-right corner to expand the digital clock to your entire screen using the browser's native Fullscreen API. Press Escape or click the icon again to exit, and your browser's own shortcut (F11 on Windows/Linux, Ctrl+Cmd+F on Mac) works too. The digits scale to any screen size and the controls auto-hide after 3 seconds, so it works well on a TV, projector, or second monitor.

Does this digital clock show accurate time?

Yes. The clock reads the current time from your device and detects your timezone automatically, so it always matches your system clock. The timezone abbreviation and UTC offset are shown below the display, and there is nothing to configure.

What font does this digital clock use?

The clock uses DSEG7, a seven-segment LCD-style font that replicates the look of classic digital alarm clocks and LCD displays. Courier New Bold is the fallback while the font loads or if it is unavailable.
