Subject: [PATCH] Avoiding return DateTime.Kind=Unspecified when converting
 from DateTimeOffset to DateTime

With this modification we would avoid getting a DateTime value (derived from a conversion from a DateTimeOffset value) that has Kind=Unspecified.
The problem is mainly evident when passing Dates as parameters of the ODATA $filter option.
With this change the conversion will aways return an UTC datetime when it is originated from a DateTimeOffset value.
