That's how you're supposed to do it. The Precision Time Protocol was fully standardized before Sonos was founded specifically intended for synchronization of media streams across different systems (among other use cases). There were other similar schemes before that. This is why RTP even has a separate timestamp field when it could simply be computed from the sequence and media codec metadata. You didn't see it much in the consumer space at the time, but the professional music production studio space had to address these concepts back in the 90s.
