time: parse 1us in Nanoseconds example

The example for Nanoseconds() currently reads:

  ns, _ := time.ParseDuration("1000ns")
  fmt.Printf("one microsecond has %d nanoseconds.", ns.Nanoseconds())

which is not terribly interesting: it seems obvious that parsing
"1000ns" and then calling Nanoseconds() will print 1000. The mention
of microseconds in the text suggests that the author's intention was,
instead, to write something like this:

  u, _ := time.ParseDuration("1us")

i.e. build a time value by parsing 1 microsecond, and then print the
value in nanoseconds. Change the example to do this.
