Is there a way to get time to be 99% or 100% accurate? time.gov shows that my Win11 and Android Pixel are off by almost a second. It'd be cool if it could grab it from the atomic clock.
- LeoPanthera 3y agoI think this is a quirk of Windows and Android machines, which do not aim for perfect precision. macOS is generally accurate to less than a tenth of a second (assuming desktops - laptops maybe less so, as they sleep a lot), and Linux will be just as accurate as long as it is running ntpd and not systemd-timesyncd.
- BenjiWiebe 3y agoI think chronyd is the one you want running on your Linux computer. IIRC it uses NTP to adjust your system clock over time for more accuracy besides just setting the time with NTP. And has more options for more time-nutty things.
- zokier 3y ago99% accurate is pretty vague, but in terms of timekeeping 1% of 24 hours is still almost 15 minutes so being off by a second is couple of orders of magnitude better. Just to give some perspective. NTP definitely should be able to keep the clock correct to sub-second level, but for more accurate local clock something like Open Time Card would do the trick, it has local atomic clock together with GPS receiver to get pretty much reference quality time.
- crote 3y agoInstall a GPS module in your computer. Your Android phone is already capable of receiving GPS, so that's probably the most readily-available accurate time source. Getting your Android phone to sync to GPS time instead of just displaying it in an app might be a bit tricky, though...
