it means that it has detected a 150 microsecond offset.

It tries originally to sleep 1000 microseconds (1 millisecond) in a loop.
It times how long the sleep lasted and compares how long it really took vs how long it was asked to sleep.
then it slowly decreases by 50 and tries again until it gets within 2 microseconds of the goal.
 
in your case of 150, it means if you subtract 150 from the total number of microseconds from all the sleeps
they will be more accurate.

This tells you the calculated average discrepancy of the timing is 150
microseconds (millisecond/1000), that I believe is good. (hope this
explanation is true ;) )
