Here you go. This is even worse. `$ time perl -MTime::HiRes=sleep -E 'say sleep 1' 1.000147 real 0m1.139s user 0m0.006s sys 0m0.008s` [download]	[reply] [d/l]

You miss the point of this test. Anonymous Monk's point is not to suggest calling out to an external perl. The point is that `sleep()` itself has inherently imprecise. You requested `sleep(1)` but actually got 1.000147 seconds of sleep. Therefore fussing over 0.00000XXXX seconds of "error" is futile. Good Day, Dean	[reply] [d/l] [select]

Therefore fussing over 0.00000XXXX seconds of "error" is futile. Yes, but the error is cumulative: 1.000147 seconds of sleep over one day amounts to an error of about 12 seconds, which might be worth fussing over...	[reply]
