Do motherboards have quartz crystals to keep track of time? Is there any other electronic method besides quartz?

>Do motherboards have quartz crystals to keep track of time?
Yes, they're usually the rounded metal rectangles you see attached to boards.
> Is there any other electronic method besides quartz?
Yes, but quartz works fine. Now that we have NTP they can be garbage, too. My system board will lose about 30 seconds an hour.

quartz isn't accurate to keep track of time. they're more likely to be used for electronic clock purposes.

Yes, it is.
Oscillators but quartz are much cheaper and have more predictable timing behavior for the dollar value in some circumstances

???? straight up nonsense.

Quartz is the defacto standard, but there are other types. And there is a difference between a resonator and an oscillator. And there are quality differences aside from those even.
Choice of crystal material, purity of crystal, design properties, and quality of components all will effect the accuracy of the "clock".
Even a cheap unregulated resonator is good enough for real-time control, as long as you have enough engineering competence to plug in a USB mouse.
As to why computer clocks seem so bad in recent years, is nothing to do with quality. Machines with multiple CPUs have always been notoriously bad about clock drift, and pretty much all machines now are multi CPU.

Is natural blue crystal better than synthetic red crystal?
>>55026002
Blue crystals run cooler. Red crystals are faster but get hot. Do not mix!

These crystals ALWAYS have drift though.
