This clock renders at approximately 60 frames per second using the browser's requestAnimationFrame API. Each frame reads the system clock via new Date() and performance.now(), which derives its time from your operating system's clock. Your OS clock is typically synchronized via NTP (Network Time Protocol) to atomic clock references, giving you accuracy within a few milliseconds of true UTC.
The stopwatch and countdown use performance.now() for monotonic high-resolution timing unaffected by system clock adjustments.
