Why do we still have so many digital clocks that run slow or fast, and need to be reset after a month or so?

Question

The one in my car runs slow and the one at work(plugged in) runs fast. My oven and microwave seem to stay accurate. Why do we have bad clocks?

Answer 1

It’s good enough for how much it costs. You can get very accurate quartz clocks, ones which compensate for the resonator changing frequency with temperature, ones which sync up with atomic clocks by radio, but those cost more and most people don’t need or want that kind of precision.
