我坚持从Elm中的Date获取当前时区偏移量.

Date.now

Run Code Online (Sandbox Code Playgroud)

这将<Thu Feb 22 2018 20:42:42 GMT+0530 (India Standard Time)>作为字符串返回 正如我在Elm的日期和时间核心库中探讨的那样,它们没有提供任何直接方法来获取当前时区偏移量.所以我该怎么做？

import Html as App
import Html exposing (..)
import Date exposing (Date)
import Task


type alias Model = 
  Maybe Date


type Msg = 
  SetDate (Maybe Date)


update : Msg -> Model -> (Model, Cmd Msg)
update (SetDate date) _ = 
  (date, Cmd.none)


view : Model -> Html Msg
view model =
  div [] [ text <| dateString model ]


dateString : Model -> String
dateString model …

我正在为我的ELM项目使用create-elm-app webpack.并通过设置代理使用代理elm-package.json,这只能在开发服务器上正常工作.当我使用elm-app buildthen代理停止在生产服务器上创建构建时 .任何人都可以建议我解决此问题的任何解决方案.

这是我的elm-package.json
