    timestamp: Date

    Timestamp when the record was logged

    value: LogRecordValue

    The logged value. For normal records, this is the actual data (number, boolean, etc.). For log-status records, this is a BACNetBitString. For time-change records, this is the number of seconds the clock changed (REAL).
