I'm usually against technical solutions for political problems, but in this case it seems like a no-brainer to switch to cheap and ubiquitous crystal oscillators to decouple timekeeping accuracy from regional political stability.
- saagarjha 9y agoThe benefits to keeping timekeeping tied to power is that often the power supply is much more accurate than any reasonably priced quartz oscillator you'd want to put into an appliance.
- zaarn 9y agoAC grid frequency is much more stable than any crystal oscillator. After any number of years, AC will, on average, drift 0 seconds from UTC. It's being sync'd using atomic clocks to keep it as perfect as possible precisely because people use it as clock.
- mcv 9y agoWhich is better depends on whether you need short term accuracy or long term. On the long term, grid clock is more accurate. In the short term, crystals are more accurate.
- contravariant 9y agoI don't think the timekeeping is the part to be concerned about.
