+This rule recommends using DateTimeOffset instead of DateTime for projects targeting .NET Framework 2.0 or later.
+Why is this an issue?
+You should use DateTimeOffset instead of DateTime as it provides all the information that the DateTime
+struct has, and additionally, the offset from Coordinated Universal Time (UTC). This way you can avoid potential problems created by the lack of
+timezone awareness (see the "Pitfalls" section below for more information).
+However, it’s important to note that although DateTimeOffset contains more information than DateTime by storing the
+offset to UTC, it isn’t tied to a specific time zone. This information must be stored separately to have a full picture of the moment in time with the
+use of TimeZoneInfo.
+How to fix it
+In most cases, you can directly replace DateTime with DateTimeOffset. When hardcoding dates with local kind, remember
+that the offset is timezone dependent, so it should be set according to which timezone that data represents. For more information, refer to
+DateTime and DateTimeOffset documentation from Microsoft (see the "Resources" section below).
+Code examples
+Noncompliant code example
+
+DateTime myDate = new DateTime(2008, 6, 19, 7, 0, 0, DateTimeKind.Local); // Noncompliant
+
+var now = DateTime.Now; // Noncompliant
+
+Compliant solution
+
+DateTimeOffset myDate = new DateTimeOffset(2008, 6, 19, 7, 0, 0, TimeSpan.FromHours(-7)); // Compliant
+
+var now = DateTimeOffset.Now; // Compliant
+
+Pitfalls
+Common DateTime pitfalls include:
+
+ - when working with
DateTime of kind Local consider the time offset of the machine where the program is running. Not
+ storing the offset from UTC separately can result in meaningless data when retrieved from a different location.
+ - when working with
DateTime of kind Unknown, calling ToUniversalTime() presumes the
+ DateTime.Kind is local and converts to UTC, if you call the method ToLocalTime(), it assumes the
+ DateTime.Kind is UTC and converts it to local.
+ - when comparing
DateTimes objects, the user must ensure they are within the same time zone. DateTime doesn’t consider
+ UTC/Local when comparing; it only cares about the number of Ticks on the objects.

+DateTime and DateTimeOffset documentation from Microsoft (see the "Resources" section below).
+Code examples
+Noncompliant code example
+
+Dim myDate As DateTime = New DateTime(2008, 6, 19, 7, 0, 0, DateTimeKind.Local) ' Noncompliant
+
+Dim now = DateTime.Now ' Noncompliant
+
+Compliant solution
+
+Dim myDate As DateTimeOffset = New DateTimeOffset(2008, 6, 19, 7, 0, 0, TimeSpan.FromHours(-7)) ' Compliant
+
+Dim now = DateTimeOffset.Now ' Compliant
+
+Pitfalls
+Common DateTime pitfalls include:
+
+ - when working with
DateTime of kind Local consider the time offset of the machine where the program is running. Not
+ storing the offset from UTC separately can result in meaningless data when retrieved from a different location.
+ - when working with
DateTime of kind Unknown, calling ToUniversalTime() presumes the
+ DateTime.Kind is local and converts to UTC, if you call the method ToLocalTime(), it assumes the
+ DateTime.Kind is UTC and converts it to local.
+ - when comparing
DateTimes objects, the user must ensure they are within the same time zone. DateTime doesn’t consider
+ UTC/Local when comparing; it only cares about the number of Ticks on the objects.
