Hi,

and a global variable that is set when you define 
the function
does not help
$time = AbsoluteTime[]
useless[] := AbsoluteTime[] - $time

Table[Pause[1]; useless[], {4}]

??

Regards

|         N[Release[y]]
|         Pause[10]
|         N[Release[y]]
|
|
| Out[49]=0.
|
| Out[51]=10.
|

| Help?
