My guess, and it has to be a guess because of the total lack of information as others have highlighted, is that your 
code (the *other* code, which you don't show) "doesn't count time" because it's running in another thread which isn't 
synchronized properly. The code you've shown is a tight, CPU bound, loop so I guess the other thread is starved of CPU 
cycles. Add your System.out and the tight loop becomes I/O bound, allowing the other thread to gain CPU cycles.

All complete conjecture based on a complete lack of information.
