My gym has about 15 different clocks on the walls, and they all tell a different time, some of them egregiously so. Every few months (often after I mention it), someone will go around and fix the worst ones.
When Daylight Savings Time began, I sauntered in about 9am and my coworkers were filtering in too. The morning guy, "Matt" had been there since about 6am and he had changed the clocks. So my other coworker, "Jason" congratulated Matt for setting all the clocks correctly and then he asked him, "so did you do it by setting all four clocks ahead one hour, or did you move them all to the left and then move the Pacific clock to the Eastern position?" Facepalm!
That might be a good job interview question, or it would have been if manual, analog clocks were still a thing.
