Revolution

A revolution is a Covenant unit of time, based on a Forerunner unit of the same name. At the time of his death, the Minister of Discovery had been serving at his post for 214 revolutions.

Trivia
Though the name of the unit implies that it equates with one revolution of High Charity (or Installation 04, for the Forerunner unit), it is unknown how this unit is standardized, as both installations are capable of moving within and between systems.
