C# 時區

Windows 時區，在 Windows 平臺實現，例："China Standard Time"
Olson（奧爾森）時區，在 Linux，Mac，IOS，Andorid，JavaScript 和許多其他平臺上廣泛實現，例："Asia/Shanghai"

如果系統不考慮全球化的話，那麼我們不用考慮時區的問題，因爲我們可以認爲中國境內的計算機全部用的是北京時間。

安裝以下兩個 Nuget 包

NodaTime
TimeZoneConverter

TimeZoneInfo

TimeZoneInfo 是一個關於時區的靜態類，可以使得我們方便的操作與時區相關的信息
對於一個開放於全球的網站或服務，在時間上的顯示是一個問題，因爲各個國家都會有所謂的時差，好在 .Net 提供了 TimeZoneInfo 類來解決這個問題。
TimeZoneInfo 類的方法可用於將一個時區的時間轉換爲其他任意時區的相應時間

靜態成員：

Local 屬性:實例化表示本地時區的 TimeZoneInfo 對象。
Utc 屬性:實例化表示 UTC 時區的 TimeZoneInfo 對象。
CreateCustomTimeZone()使用應用程序提供的數據創建自定義時區。 - CreateCustomTimeZone 方法創建在本地系統註冊表中未定義的時區。然後可使用 ToSerializedString 屬性將時區對象的信息保存爲字符串，該字符串可以以應用程序可訪問的某種格式存儲。使用 FromSerializedString 方法可將序列化字符串轉換回 TimeZoneInfo 對象
FindSystemTimeZoneById()根據時區的標識符實例化在系統註冊表中定義的時區。
FromSerializedString()反序列化一個字符串值，以重新創建先前已序列化的 TimeZoneInfo 對象。
GetSystemTimeZones()返回 TimeZoneInfo 對象的可枚舉的 ReadOnlyCollection<(Of <(T>)>)，它表示本地系統上可用的所有時區。

獲取 TimeZoneInfo

//.net 自帶
Console.WriteLine(TimeZoneInfo.Local);//服務器時間
Console.WriteLine(TimeZoneInfo.Utc);//UTC時間


//TimeZoneConverter
Console.WriteLine(TZConvert.GetTimeZoneInfo("Central Standard Time"));//中部時間(美國和加拿大)
Console.WriteLine(TZConvert.GetTimeZoneInfo("America/New_York"));//美國時間
Console.WriteLine(TZConvert.GetTimeZoneInfo("Asia/Shanghai"));//上海時間

時間轉換

TimeZoneInfo timeZoneInfo = TimeZoneInfo.FindSystemTimeZoneById("China Standard Time");
DateTime dateTime = TimeZoneInfo.ConvertTime(DateTime.Now, timeZoneInfo);

DateTime dt = TimeZoneInfo.ConvertTimeToUtc(DateTime.Now, TimeZoneInfo.Local);
DateTime dt1 = TimeZoneInfo.ConvertTimeFromUtc(dt, timeZoneInfo);


//NodaTime方式
Instant now = SystemClock.Instance.GetCurrentInstant();
var shanghaiZone = DateTimeZoneProviders.Tzdb["Asia/Shanghai"];
var shanghaiZone2 = NodaTime.DateTimeZoneProviders.Tzdb.GetZoneOrNull("America/New_York");
DateTime dateTime3= now.InZone(shanghaiZone).ToDateTimeUnspecified();

sqlserver 存儲時間

推薦 sqlserver 中使用：datetime2。

date：3字節，表示範圍：0001-01-01 到 9999-12-31
datetime：8字節，表示範圍： 1753-01-01 00:00:00 到 9999-12-31 23:59:59
datetime2：6-8個字節，表示範圍：0001-01-01 00:00:00 到 9999-12-31 23:59:59.9999999
smalldatetime：4個字節，表示範圍：1900-01-01 00:00:00 到 2079-06-06 23:59:59
time：5個字節，表示範圍： 00:00:00.0000000 到 23:59:59.9999999
datetimeoffset：10個字節，表示範圍：0001-01-01 00:00:00 到 23:59:59.9999999，可表示時區
