A time when one feels it most polite to retire to a quiet space for a half hour slumber.

A short rejuvenating snooze.
Corporal: "Sir, the Germans are advancing on our front lines as we speak"

Captain: "How long do we have, old boy?"

Corporal: "Just under an hour, sir"

Captain: "Not to worry, my good man, Ill still have time for A Gentleman's Half Hour in that case, before the battle"
