Interesting question. If miners are approximately evenly distributed across timezones, it could be indeed the case, say, that those where demand is currently at its peak (following the sunlight) switch off their mining as electricity is expensive, and then switch back on as the sun leaves and electricity demand (and prices) fall. I had assumed that mining is concentrated more. Empirical question.
