Sunday, one of the kids asked how Daylight Saving Time came to be (a disgruntled kid, I should add, since she’d be waking for school an hour earlier the next morning). I spared her my discourse on a subject I’m peculiarly fascinated by and gave her the short version: Several countries adopted it in World War I as a way to save coal for the war effort. Most dropped it following the war, resumed it for WWII, then, to a large extent, stuck with it.
