Differences in Call Time calculations

[madonnac]

I have 2 reports (designed by different people) that use 2 separate calculations to work out total call time (without ACW)

One uses
ACDTIME + HOLDTIME

The other uses
i_acdtime + i_acdothertime + i_acdaux_outtime

Looking at the definitions in the Avaya help file, they would seem to be equivalent, bit I am seeing discrepancies.
Which one (if any) would be considered correct, and if neither, what should be the correct definition?

Are both reports interval reports?

yes, and I can edit both reports to show the other calculation, which shows the discrepancies.
