Is sleep method accurate in timing precision?

Question

We all know of sleep method available in java threads.. I understand that the precision in timing depends on the precision of hardware clock in the system.. So my question is how accurate is this method or better say what is the error in milliseconds or nanoseconds considering a general pc.

My requirement its to synchronise data transfer using sleep for timing.. The data is to be sent in fixed in intervals (10-20 millis) and if there is a delay of more than 1sec due to successive error in timing it may be bad !

So is it advisable to use the also method?

Answer 1

Sleep is not the thing you want, as in here. I suggest to read through this.
