Those nanoseconds aren't really entropy then, are they?

  They're entropy for most practical purposes. But there's only 1000 possibilities, so that's less than 10 bits' worth.

    Especially if you're writing a file, the creation time is a big hint! Even nanoseconds won't help if you're leaking that many bits from your seed.

    That's milliseconds; nanoseconds are 1e-9 seconds. Still, the file creation time remark of sibling is pertinent.

      I was thinking of the step from milli to nano, so yeah 1e6 not 1e3, 20 bits not 10. But the point stands.
