And in addition, the lowest temperature of the day usually occurs right near or just after dawn, so filtering it to "daytime" temperatures being when the sun is up would basically include roughly the coldest (and hottest) temperature of the day anyways.

So while I've never interacted with this specific metric, everything suggests to me that you would just use the values over a standard 24 hour day.
