Chronometer

A chronometer is an instrument for measuring time accurately. In this online context, it's a digital stopwatch that allows you to measure elapsed time with precision down to milliseconds.

This chronometer uses your device's internal clock and JavaScript's timing functions. While it's precise enough for most everyday timing needs, it may not be suitable for scientific measurements that require extreme precision due to variations in browser performance and system load.

Yes, the timer will continue running if you switch to another tab or minimize your browser. However, the display might not update until you return to this tab, at which point it will catch up to show the correct elapsed time.
