I tried this:
----------------------------------------------------------------------
/usr/home/seggers 538$ time ls -lLtr Mail|wc
44 389 2588
real 0m0.060s
user 0m0.026s
sys 0m0.016s
/usr/home/seggers 539$ time ls -lLtr Mail|wc
44 389 2588
real 0m0.060s
user 0m1.007s
sys 0m0.035s

I am using bash 2.0.x on FreeBSD 2.2-stable from last weekend for
this. It can't even decide how long it wants to take!
As I thought it might be an effect of running multi user with alot of
daemons I did it again single user and the result was the same. I
found no pattern in it.
Funny. I now can't get it to take long again. And once it used no
user time at all. The latter at least one can explain. Some time
inaccuracy due to rounding somewhere. But what in hades causes the
additional second?
Stefan.
