    blk-iolatency: truncate our current time · 71e9690b

    In our longer tests we noticed that some boxes would degrade to the
    point of uselessness.  This is because we truncate the current time when
    saving it in our bio, but I was using the raw current time to subtract
    from.  So once the box had been up a certain amount of time it would
    appear as if our IO's were taking several years to complete.  Fix this
    by truncating the current time so it matches the issue time.  Verified
    this worked by running with this patch for a week on our test tier.
