     * reading of all samples within the period as well as the most
     * critical state.
     *
     * Record IDs start at 1 and grow continuously without wrap-around. To
     * avoid race conditions it is allowed to request records that are no
     * longer available, i.e. have rotated out of the log. Unavailable
     * records come back empty (available = false, timestamp = 0). It is
     * not OK to read past newestRecId.
     *
     * Log record periods are synchronized with the system time, so all
     * devices with the same log settings and proper time configuration
     * move to a new record simultaneously.
