time.Duration's method can not completed automaticly and can not go-to-define

sample code

package main

import (
    "testing"
    "time"
)

var (
    interval1 = time.Second
    interval2 = 5 * time.Second
)

func TestIdeaTimeApi(t *testing.T) {
    t.Logf("%T %T", interval1, interval2)
    t.Logf("%d %d", interval1.Nanoseconds(), interval2.Nanoseconds())
}

output is:

/usr/local/go/bin/go test -v testgolang -run ^TestIdeaTimeApi$

And I found godef does not work either on this scenario.
