About the clock, timer & stopwatch
Three time tools in one place. The clock shows local time and date in your choice of 12 or 24 hour format. The countdown timer takes hours, minutes and seconds, offers one-tap presets and sounds an alert when it reaches zero. The stopwatch records laps with per-lap and cumulative splits, and both keep accurate time even when the tab is backgrounded because they track wall-clock timestamps rather than counting ticks.
This tool runs entirely in your browser. Nothing you type is uploaded, and it keeps working with no connection at all — including as an installed app.
