I'm still working on getting this to work, but the summary is this: I am getting several (many) intervals of hour, minutes and seconds. I need a sum of the absolute value these intervals, similar to the SUM(ABS()) function for numbers; and I need to divide this sum by an integer (bigint). Getting the intervals is no problem, but I can't find built in functions for the rest. Currently on 8.3, want to upgrade to 9.x but I can't until this is finished.
Do these functions exist, or will I be forced to convert to seconds, do the math and then convert back to hour-minute-second format (I am assuming from current data that, after the divide, the result should be in the minute: second range).
