JFR timestamps are calculated in the following manner. timestamp = chunkStartTime + (jfrTicks - chunkStartTicks) The reason the data seemed sensible is because we always made the chunkStartTicks zero in the chunk header, so the relative difference in the millisecond time entries made some sense, but this was incorrect.
