Say you call x which call x which calls x. I'll refer to function instances as
x1, x2 and x3 ;

Cumulative time for x will include
net time for x3 +
net time for x2 + total time for x3 +
net time for x1 + total time for x2
and this is equal to
net time for x1 + 2 * net time for x2 + 3 * net time for x3.

You're counting the same time several times!
