Please answer these questions before submitting your issue. Thanks!

  1. What version of Go are you using (go version)?
    go version go1.6 darwin/amd64
  2. What operating system and processor architecture are you using (go env)?
    GOARCH="amd64"
    GOBIN=""
    GOEXE=""
    GOHOSTARCH="amd64"
    GOHOSTOS="darwin"
    GOOS="darwin"
    GOPATH="/Users/thinkhy/go"
    GORACE=""
    GOROOT="/usr/local/Cellar/go/1.6/libexec"
    GOTOOLDIR="/usr/local/Cellar/go/1.6/libexec/pkg/tool/darwin_amd64"
    GO15VENDOREXPERIMENT="1"
    CC="clang"
    GOGCCFLAGS="-fPIC -m64 -pthread -fno-caret-diagnostics -Qunused-arguments -fmessage-length=0 -fno-common"
    CXX="clang++"
    CGO_ENABLED="1"
  3. What did you do?
    If possible, provide a recipe for reproducing the error.
    A complete runnable program is good.
    A link on play.golang.org is best.
import (
        "encoding/json"
        "time"
        "os"
)


type Response struct {
        Name     string    `json:"name,omitempty"`
        Counter  int       `json:"counter,omitempty"`
        CreateAt time.Time `json:"createat,omitempty"`
}


func main() {
        var r Response

        enc := json.NewEncoder(os.Stdout)
        enc.Encode(r)
}
  1. What did you expect to see?

Seems the expected result should be "{}" because the field createat is empty with ZERO value.

  1. What did you see instead?

The above code will output:

   {"createat":"0001-01-01T00:00:00Z"}
