Why is the amount of time shown in the detail report sometimes not the same as the icon time?
In the executive summary (the Details tab), time is measured in fractions of an hour (2 decimal places). Time for icons is measured in seconds, and can be displayed in either hms format or fractions of an hour. Check which settings you are using, and remember that for fractions of an hour with only 2 d.p., you will get small rounding errors.
