# enet.peer:round trip time

Returns or sets the current round trip time (i.e. ping). If value is nil the current value of the peer is returned. Otherwise the round trip time is set to the specified value and returned.

ENet performs some filtering on the round trip times and it takes some time until the parameters are accurate. To speed it up, set the last round trip time to an accurate guess.
