Frequently asked questions
- Is this clock accurate?
- It reads your device's clock, so it's as accurate as your OS time. Most modern devices sync to NTP servers automatically and stay within a few hundred milliseconds of UTC.
- Why does my time zone matter?
- The clock displays time in your system's configured time zone (shown below the clock). If you're traveling and your laptop hasn't updated, the clock will show whatever your OS thinks the local time is.
