I am not follow timestamps printed in GC log of Oracle JDK 1.6.
Looking at

   [PSYoungGen: 699458K->22193K(743680K)] 886054K->233354K(3039488K),
0.0437840 secs]
   [Times: user=0.29 sys=0.01, real=0.04 secs]

The user space time is 0.29seconds, while the wall clock time us only 0.04s.
How can this be. should not wall clock time ("real") include time spent in
user space
("user") and in the operating system ("sys").

thanking you,
