Hi mum [1],

At each run, your test case almost always starts with the same value:

$ gcc -o ct ct.c

$ ./ct
tv_sec = 0, tv_nsec = 2793
tv_sec = 0, tv_nsec = 999989104
tv_sec = 2, tv_nsec = 15365
tv_sec = 3, tv_nsec = 17879

$ ./ct
tv_sec = 0, tv_nsec = 2793
tv_sec = 0, tv_nsec = 999990222
tv_sec = 1, tv_nsec = 999997765
tv_sec = 3, tv_nsec = 3911

$ ./ct
tv_sec = 0, tv_nsec = 2793
tv_sec = 0, tv_nsec = 999987428
tv_sec = 2, tv_nsec = 5587
tv_sec = 3, tv_nsec = 11453

$ ./ct
tv_sec = 0, tv_nsec = 2793
tv_sec = 0, tv_nsec = 999989942
tv_sec = 1, tv_nsec = 999996088
tv_sec = 3, tv_nsec = 2514

$ ./ct
tv_sec = 0, tv_nsec = 2793
tv_sec = 0, tv_nsec = 999990222
tv_sec = 2, tv_nsec = 4190
tv_sec = 3, tv_nsec = 11733

$ ./ct
tv_sec = 0, tv_nsec = 3073
tv_sec = 0, tv_nsec = 999989942
tv_sec = 1, tv_nsec = 999996926
tv_sec = 3, tv_nsec = 3911

[...]

I wonder if this is to be expected...

and, Tobias, why your test case [2] prints always "0" [3]? it looks very 
similar to that of Corinna.. oops mum.. ;-)


Ciao,
  Angelo.
