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,

    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...

      The error is not cumulative in the OP code nor most of the suggestions.

      Good Day,
