如何将unix时间戳格式化为RFC3339-Golang?

I need to convert a unix timestamp ( e.g 1392899576 ) into RFC3339 ( e.g. 1997-07-16T19:20+01:00 ) . I've tried the code below

    timeValue := "1392899576"
    layout := time.RFC3339
    t, _ := time.Parse(layout, timeValue)

    fmt.Fprintf(w, "%s", t)

which returns

0001-01-01 00:00:00 +0000 UTC

The term "Parse" usually means a procedure that converts a string representation of something into the internal language representation for the same thing.

What you want is the opposite of Parse, "Format":

time.Unix(1392899576, 0).Format(time.RFC3339)
