我認為最好從目標開始：NSYE opens at 09:30:00 - It opens in X minutes/It closes in Y minutes.LSE opens at 08:00:00 GMT - It opens in X minutes/It closes in Y minutes.當前代碼：type StockExchanges map[string]stringfunc showOpeningTime() { for stockExchanges, stockExchange := range map[string]StockExchanges{ "NYSE": { "open": "09:30:00", "close": "16:00:00", "location": "America/New_York", }, "LSE": { "open": "08:00:00", "close": "16:00:00", "location": "Europe/London", }, } { currentTime, err := TimeIn(time.Now(), stockExchange) if err == nil { ///////CODE HERE////// } else { fmt.Println(stockExchange, "<time unknown>") } } return}func TimeIn(t time.Time, stockExchanges StockExchanges) (time.Time, error) { loc, err := time.LoadLocation(stockExchanges["location"]) if err == nil { t = t.In(loc) } return t, err}因此，對于其時區的用戶，我想看看所有股票交易所的開盤時間之前需要多長時間。currentTime例如：假設您在GMT，紐約證券交易所直到，所以假設當前時間是，我希望輸出是：14:30:00 GMT14:29:00 gmtNSYE opens at 09:30:00 - It opens in 00:01:00 minutes.LSE opens at 08:00:00 GMT - It is currently open.我正確地獲取了用戶的時間區，它返回一個包含偏移量的時間對象。我的解決方案可以完全改變。去時區
