Is it actually worse or do we just have a different standard for "good job"? The AC clock on my oven definitely drifts by a couple minutes every once in a while, but it's a lot better than the mechanical clocks I remember as a kid. Yet it's still good enough that I've never seen my UPSes report anything other than 60.0hz
