 displayTime: {
      // set and get is useful when the data
      // returned by the back end api is different from the front end
      // back end return => "2013-06-25 06:59:25"
      // front end need timestamp => 1372114765000
      get() {
        return (+new Date(this.postForm.display_time))
      },
      set(val) {
        this.postForm.display_time = new Date(val)
      }
    }
