Thread Wait Time The total amount of thread wait time. It is an integer in the range 09 - 99999999 seconds. Note: collection of thread time requires activation of Accounting Class 2 in the Monitored DB2 subsystem.
Time Stamp Represents the end of data collection or the end of an interval, and is the local time where the system is running.
The timestamp format for SCAN and STR functions is CYYMMDDHHMMSSmmm (as in 1180315064501000 for 03/15/18 06:45:01) where: C = Century (0 for 20th, 1 for 21st), Y = Year, M = Month, D = Day, H = Hour, M = Minute, S = Second, m = Millisecond.
