Previously, the time generation code would inexplicably drop parts of
the nanotime -- potentially causing validation to succeed when it should
fail. This was probably do to a bug in the remainder logic, but instead
we should be using .Nanosecond() anyway.
After changing the time of a file with a test case like this:
// Change the time to something known with nanosec != 0.
chtime := time.Unix(100, 987654321)
if err := os.Chtimes("somefile", chtime, chtime); err != nil {
// panic
}
timeKeywordFunc() would return the wrong value (time=100.000000021).
This fixes the issue and adds a test case.
