So the operating system can use it to derive its notion of time. It helps computer to keep the time correct. But a bad oscillator could be influenced by the heat of CPU, like compiling Linux kernel, etc. A really high-quality oscillator would be really expensive. So most computers come with fairly bad oscillators. ...
