## Apple RunTime Tags

This PLIST-format information contains the elements of a CMTime structure representing the amount of time the phone has been running since the last boot, not including standby time.

> Tag ID | Tag Name | Writable | Values / Notes
> --- | --- | --- | ---
> 'epoch' | RunTimeEpoch | no |
> 'flags' | RunTimeFlags | no | Bit 0 = Valid Bit 1 = Has been rounded Bit 2 = Positive infinity Bit 3 = Negative infinity Bit 4 = Indefinite
> 'timescale' | RunTimeScale | no |
> 'value' | RunTimeValue | no |
