MoQ Object Timestamp Extension rev 00 lands on the IETF Datatracker
This document defines an extension for MoQ Transport [moqt] that attaches a media presentation timestamp and duration to each object. A track-level Timescale property establishes the units, an object- level Timestamp property carries the presentation time of each object, and an optional Duration property carries its presentation duration. Exposing media time to the transport lets relays make consistent age-based decisions (e.g. dropping stale objects) without parsing the media container, and it remains consistent across hops regardless of buffering or jitter.

Summary
This document defines an extension for MoQ Transport [moqt] that attaches a media presentation timestamp and duration to each object. A track-level Timescale property establishes the units, an object- level Timestamp property carries the presentation time of each object, and an optional Duration property carries its presentation duration.

Analysis
This draft is directly relevant to the MOQ ecosystem and worth tracking because it reflects current protocol work or adjacent implementation guidance from the IETF process.
