[SLUG] Error in Time() command

["tenzero@xxxxxxxxxxxx" <tenzero@xxxxxxxxxxxx>]

Hi everyone,

I'm seeking a preferably citeable reference to the amount of error in the returned result from a Time() command. I want to be 
able to quote the level of error in timing the execution speed of my project.

While I have been using this command partly on Ubuntu for my project, I would particularly like to find out the level of this error 
on Mac OS X. Google and Google scholar have been disapointing.

I concede that this is a little off topic and will move it OT if people are unhappy.

Cheers.
D.
