What did you do?

I have created an empty package and a SWIG interface for it containing only %go_import(_ "time").

What did you expect to see?

A successful build (by doing go build).

What did you see instead?

The build failed with the following error:
/tmp/go-build220377569/b001/_dummy_swig.go:40:8: can't find import: "time"

Files to reproduce this issue: dummy_test.zip

I believe this can be explained by

go/src/cmd/go/internal/load/pkg.go

Line 1657 in 98d2717

// TODO: The .swig and .swigcxx files can use

A workaround for this is to add import _ "time" on the go file.
