One thing we noticed is that if the person is currently online those #'s do
not show up in the Time on function within Emerald

AcctSessionTime

>In my testing scenario, the following numbers apply: (These are actual

> Calls.AcctSessionTime = 105433
>Following through the calculations: (SQL Auto rounds to 0 decimal places)
> 105433/3600 = 29
> Total Hours
> (105433/60) - [(105433/3600) * 60]
> (SQL Rounds) - [(SQL Rounds)*60]
> 1757 - 29*60 = 17

included).
