Floating Clock

The ZeoTools Floating Clock opens a real, separate window that holds nothing but the time and the date, and keeps it above whatever you are working on. It is built on the Document Picture-in-Picture API, the same mechanism that lets a video pop out of a page and hover over your desktop, except the window is filled with a clock instead of a video. Because it is a browser feature rather than a program, there is nothing to download and nothing to install, which makes it usable on locked-down work machines where installing software is not an option. Everything runs inside the tab, the same browser-side approach our 2FA Code Generator uses to build codes without ever contacting a server.

Why an always on top clock? A clock in the corner of the screen is easy to miss when a document, a spreadsheet, or a full-screen video is covering it, and the taskbar clock disappears entirely the moment an application goes full screen. A floating window sits above all of that. It is useful while recording or streaming, during timed exams and interviews, when you are working to a hard deadline, or while you wait for a long audit to finish in Web Inspector. The time and time zone are read from your own device, so a visitor in Jakarta and a visitor in New York each see their own correct local time without configuring anything. The date line is a separate choice and can be written in Indonesian or English, whichever time zone you happen to be in.

How it stays readable: The digits use tabular figures, meaning every digit is given the same width, so the clock does not shuffle sideways each second the way a proportional font would. Letter spacing is widened slightly on both lines, the time carries a soft vertical gradient for depth, and three themes are available so the window can sit comfortably against a bright desktop or a dark one. The window can be resized to any size you like and the type scales with it, in the same spirit as the viewport switching in our Live Mobile tester.

Privacy: Everything runs inside your browser. The clock reads your system time and nothing else, sends no request to ZeoTools while it is running, and stores only your language, theme, and window size in your own browser.
