Change "/ NS_PER_S" to "* S_PER_NS" fixing a conversion problem.
In this instance NS_PER_S replaced 1e9 with 1000000000, and that
caused integer instead of float arithmetic which caused precision
errors. This change fixes that error and repalces division with
multiplication.
Yet another case where the warning messages we ignore woulda
alerted about the problem.
