Advances the last buffer pointer and returns a buffer to be used for new data.
Advances the last buffer pointer and returns a buffer to be used for new data. In the beginning this is an unused buffer, after the ring fills, it returns the oldest buffer If the time parameter matches the most recent buffers time, that buffer will be re-used.
