The low order 32 bits of the accumulated squares of completion times (in milliseconds) of NQA operations which complete successfully. Low/High order is defined where the binary number will look as follows: ************************************************* | High order 32 bits | Low order 32 bits | ************************************************* For example the number 4294967296 would have all Low order bits as '0' and the rightmost High order bit will be 1 (zeros,1).
