I would expect so, assuming it provides the level of timing precision you're interested in, and you don't mind the manipulation it does (adding the proxy header, potentially re-framing the stream into different packets, etc.).

You could just capture all the data and analyze it out-of-band. pcap has reliable millisecond time resolution (pcap-ng has nanosecond resolution on platforms that support it), you can filter to capture only relevant traffic, and there are lots of tools to help with the analysis.
