UTC to locatime with daylight saving

Question

We are saving all dates in UTC in our database and also saving offset for each user.

We are converting to localtime by following function:

 Private Function ConvertToLocalDateTime(ByVal utcOffset As Integer?, ByVal DateToConvert As DateTime?) As DateTime?

        getdatetime = DateToConvert.Value.AddHours(utcOffset)

        If getdatetime.IsDaylightSavingTime Then
            getdatetime.AddHours(-1)
        End If

        Return getdatetime
    End Function

But still dates are 1 or 2 hours off.

How can we convert correctly to localtime from utcoffset also taking care of daylight saving?

Answer 1

只要将DateToConvert的Kind属性正确设置为Utc ，您就可以调用DateToConvert.ToLocalTime() 。
