At MSDN page for Stopwatch class I discovered link to interesting article which makes following statement about Stopwatch:

However there are some serious issues:

This can be unreliable on a PC with multiple processors. Due to a bug in
the BIOS, Start() and Stop() must be executed on the same processor to get a correct result.

This is unreliable on processors that do not have a constant clock speed (most processors can reduce the clock speed to conserve energy). This is explained in detail here.

I am little confused. I've seen tons of examples of using Stopwatch and nobody mention this drawbacks. How serious is this? Should I avoid using Stopwatch?
