我在sqlite數據庫中保存了一個日期。知道我嘗試獲得小時和分鐘。從NSDate獲取小時數
Europe/Berlin (GMT+2) offset 7200 (Daylight)
2016-08-17 18:44:57 +0000
the hour is 20 and minute is 44
2016-08-18 18:44:57 +0000
the hour is 20 and minute is 44
2016-08-19 15:44:57 +0000
the hour is 17 and minute is 44
2016-08-18 16:44:57 +0000
the hour is 18 and minute is 44
2016-08-17 18:44:57 +0000
the hour is 20 and minute is 44
2016-08-18 18:44:57 +0000
the hour is 20 and minute is 44
2016-08-19 15:44:57 +0000
the hour is 17 and minute is 44
2016-08-18 16:44:57 +0000
the hour is 18 and minute is 44
的時區是正確的:就是工作時間由2
print(calendar.timeZone)
while result.next() {
var hour = 0
var minute = 0
let calendar = NSCalendar.currentCalendar()
if #available(iOS 8.0, *) {
calendar.getHour(&hour, minute: &minute, second: nil, nanosecond: nil, fromDate: result.dateForColumn("time"))
print(result.dateForColumn("time"))
print("the hour is \(hour) and minute is \(minute)")
}
}
我得到以下輸出偏移。我嘗試了另外兩種解決方案。但它總是同樣的問題。
沒有問題,輸出是正確的。 'print(someDate)'用UTC打印,日期組件在你的本地時區。 –
