zx::time NextSynchronizedTimestamp (zx::time min_time)Returns a timestamp in the future that corresponds to byte 0 of the ring buffer.
The returned time is guaranteed to be at least min_time in the future, even if that
means waiting for more than one round trip through the ring buffer.

int64_t RingBufferFrameAtTimestamp (zx::time ref_time)Returns the absolute ring buffer frame number corresponding to the given time. The
"absolute" frame number starts at zero and increases monotonically. The actual ring
buffer offset is given by absolute_frame_number % ring_buffer_size.
