    o = o.Local()
    t, ok := time.ParseInLocation("2006-01-02 15:04:05", "2017-10-30 00:01:49", time.Local)
    if ok != nil {
        fmt.Printf("Could not parse")
    } else {
        fmt.Printf("Now in nano : %d ", t.UnixNano())
    }
    t = t.Local()
    n := time.Unix(0, t.UnixNano())
    fmt.Printf("Original : %s, Converted back : %s\n", t.Format(time.RFC3339Nano), n.Format(time.RFC3339Nano))
    if ok != nil {

The native backend was never fixed.

Oh, I see. Could we rename / alias this from native to delve instead? It's still confusing for me which is which without checking the code. I'll update the issue on GoLand's side. Thank you for the quick reply.

[aarzilli]

default is already aliased to the "right" backend on all platforms.
