time builtin

I just observed this broken behaviour in 3.0.0 and 3.1.0.
The real time reported by builtin time (%E) is almost
always less than %U + %S. A quick test shows that this
behaviour is not present in 2.6-beta13.
Now printtime() in 2.6-beta13 had this code:
if (percent > 100)
percent = 100; /* just to make it look right */
but that was removed in 3.0.0. Reinserting those two lines
in 3.0.0 obviously ``fixes'' the problem, or perhaps it is
more accurate to say that it hides the real problem again.
Is it possible to fix this, or are the times here just to
close to the resolution provided by the kernel?
