转换后得到不正确的日期格式

Question

我从 API 中获取字符串格式的日期：“2020-01-02T00:00:00”。

现在我想把这个日期转换成Date格式。所以这就是我为此所做的...

var utcTime = "\(dic["Due_Date"]!)" //Printing `utcTime` gives "2020-01-02T00:00:00"
self.dateFormatter.dateFormat = "yyyy-MM-dd'T'HH:mm:ss"
self.dateFormatter.locale = Locale(identifier: "en_US")
if let date = dateFormatter.date(from:utcTime) {
  self.scheduledDate = date //HERE I GET THE DATE AS 2020-01-01 18:30:00 UTC
}

收到的字符串格式日期为“2020-01-02T00:00:00”。但是当我将它转换为 Date 格式时，我得到的日期是 2020-01-01 18:30:00 UTC，这是不正确的。

Answer 1

您还需要设置时区。

let utcTime =  "\(dic["Due_Date"]!)"
let dateFormatter = DateFormatter()
let timezone = TimeZone.init(secondsFromGMT: 0)

dateFormatter.dateFormat = "yyyy-MM-dd'T'HH:mm:ss"
dateFormatter.timeZone = timezone!

if let date = dateFormatter.date(from:utcTime) {
  print(date) // 2020-01-02 00:00:00 +0000
}

Answer 2

 let inputDate = "2020-01-02T00:00:00"

let dateFmt = DateFormatter()
dateFmt.dateFormat = "yyyy-MM-dd'T'HH:mm:ss"

if let date = dateFmt.date(from: inputDate) {
    //IF YOU NEED TO CHANGE DATE FORMATE
    dateFmt.dateFormat = "dd-MMM-yyyy"
    print(dateFmt.string(from: date))
}

Answer 3

您必须将时区设置为 UTC（协调世界时）

var utcTime = "2020-01-02T00:00:00" //Printing `utcTime` gives "2020-01-02T00:00:00"
let dateFormatter = DateFormatter()
dateFormatter.dateFormat = "yyyy-MM-dd'T'HH:mm:ss"
dateFormatter.locale = Locale(identifier: "en_US")
dateFormatter.timeZone = TimeZone(abbreviation: "UTC")
if let date = dateFormatter.date(from:utcTime) {
  print(date)  //HERE I GET THE DATE AS 2020-01-01 18:30:00 UTC
}

输出：-
