 - **Send time** - The time at which the message can next be offered or sent to the peer, or zero if the message has never been offered or sent to the peer (`expiry`)
 
-- **Expected arrival time** - The time at which the offer or message is expected to arrive at the peer, or zero if the message has never been offered or sent to the peer (`eta`)
+- **Max latency** - The maximum latency of the transport that was last used to send the message (`maxLatency`)
 
 The device may also store a list of message identifiers that have been offered by the peer and not yet requested by the device. This list allows requests to be sent asynchronously. The length of the list may be bounded and the peer may discard offered message identifiers when the list is full.
