or at least just local time zones. I imagine it this way:
Peasant Bob: Hey, look, the sun’s all the way up in the sky.
Scholar Jake: That means it’s noon, idiot.
(later)
Peasant Bob: Hey, look, the moon’s all the way up in the sky.
Scholar Jake: That means it’s midnight, idiot.
(later)
Son of Peasant Bob: What’s Daylight Savings Time?
Son of Scholar Jake: There’s no such thing, idiot.
