Question: time() not consistant

The time function doesn't seem to be working consistantly.

Following the example in the help page for the time() function I can't get as low as .041.  The best I get is .046 and sometimes .047 .062 and .063.  Are there services running in the background that can affect the run performance like a firewall for example?

Can anyone else get .041?  For comparison I'm using a P4 - 3 GHz. and 2.5 Gb RAM @ 533 MHz. with 48 processes running in the task manager.

Not that it really matters but why do the times vary?  Should I not get the same result.  And why is it only relevant to 3 decimal places?
