What

EpochChanged events emitted by syscallOnEpochChange at the end of epoch delay rounds. Marks the transition between epochs. At this point: pending stake changes from previous epoch become active, accumulator values are saved for validators with stake changes, and inactive validators are removed from consensus set. Epochs are variable length (~5.5 hours) based on consensus rounds, not fixed block counts.
