Resolution
SQLSUM request is in R180.CDBATREQ(SQLSUM) member.
The format of fields AVG DUR and AVG CPU is 'MM:SS.TTTT'.
HH:MM:SS.TTTT specifes hours, minutes, seconds and ten-thousandths of seconds.
Please see the following link for an explanation about how TTTT should be read:
Field-Attrib
https://docops.ca.com/ca-sysview-db2/19/en/reference/iql-reference/iql-syntax/request-elements/field-specification/field-attrib
T - seconds (tenths)
TT - seconds (hundredths)
TTT - milliseconds
TTTT - milliseconds (tenths)
Sample panel displays.
AVG DUR: 1.0500 --> 1 second and 5 hundredths seconds (Or 1050 milliseconds).
AVG DUR: 1.5000 --> 1 second and 5 tenths seconds (Or 1500 milliseconds).
AVG DUR: 0.0010 --> 1 millisecond.
