執行緒安全性

此類型的所有成員都是安全線程。看似修改實例狀態的成員，實際上會傳回以新值初始化的新實例。如同任何其他類型，讀取和寫入包含此類型實例的共用變數必須受到鎖定保護，以確保線程安全。

DateTimeOffset

TimeSpan

Calendar

GetUtcOffset(DateTime)

TimeZoneInfo

在 DateTime、DateTimeOffset、 TimeSpan 和 TimeZoneInfo 之間選擇使用行事曆 Sample: .NET Core WinForms Formatting Utility (C#) (範例：.NET Core WinForms 格式化公用程式 (C#)) Sample: .NET Core WinForms Formatting Utility (Visual Basic) (範例：.NET Core WinForms 格式化公用程式 (Visual Basic))
