Instance Property

epoch

The epoch of the CMTime.

Declaration

var epoch: CMTimeEpoch

Discussion

You use the epoch to differentiate between equal timestamps that are actually different because of looping, multi-item sequencing, and so on.

The epoch is used during comparison: greater epochs happen after lesser ones. Addition or subtraction is only possible within a single epoch, however, since the epoch length may be unknown or variable.
