Convert DateTimeOffset to DateTime

Thank you, what is Power Query equivalent to .NET TimeZoneInfo.FindSystemTimeZoneById ? My Settings table stores Time Zone info by using standard IDs, like Pacific Standard Time and I need to convert values in my DateTimeOffset column to the time zone stored in the Settings table, this is how I do that in C#:

TimeSpan timeZoneOffsetSpan = TimeZoneInfo.FindSystemTimeZoneById(settings.TimeZone).GetUtcOffset(UserCreatedDateTime);

This gives me a difference between the time in the time zone stored in my Settings table and UTC for UserCreatedDateTime. And I am executing that line of the code just once for all rows in my User table because the purpose of the code above is to find out current offset taking into account such timezone's features like DayLightSaving.

And now I can simply add that offset (which could be positive or negative) against every value in my User.CreateDateTime column, in C# I am doing that by using DateTimeOffset.ToOffset:

DateTimeOffset convertedOffset = UserCreatedDateTime.ToOffset(timeZoneOffsetSpan)

So I need to be able to do the same conversions in my Power BI report but I couldnot find any Power Query function which can do the same what TimeZoneInfo.FindSystemTimeZoneById does, if that function existed it would cover my first line of C# code and then I would need to find an equivalent to TimeZoneInfo.FindSystemTimeZoneById. DateTimeZone.SwitchZone is probably what I need but I first need to know the offset corresponding to my time zone and then I would be able to supply that offset as 2nd and 3rd parameters to that function.

So, to finalize, I need Power BI analog for TimeZoneInfo.FindSystemTimeZoneById
