Unity Script Reference – NetworkMessageInfo.timestamp

NetworkMessageInfo.timestamp

var timestamp : double

Description

The time stamp when the Message was sent in seconds.

Timestamps can be used to implement interpolation or extrapolation of continous streams of packets The timestamp is passed as a double to avoid overflow when a game is running for a long time. Internally timestamps are sent as 32 bit integers with millisecond accuracy to save bandwidth. Timestamps are automatically adjusted to be relative to Network.time. Thus Network.time - messageInfo.timeStamp is the time the packet spent in transit.
