Getdate in UDF

Hi,

My question is: can I use GETDATE function in  scalar UDF as below:

CREATE FUNCTION dbo.GetDateFunction()

RETURNS DateTime

AS

BEGIN

   RETURN GetDate();

END

I have seen this UDF definition in tutorial,but I thought non-deterministic functions can not be used in UDF.

I also looked at two sites to find out but both says differently:

Technet:

https://technet.microsoft.com/en-us/library/aa175085(v=sql.80).aspx

states that functions that return different values on each call can not be used in UDF.

MSDN:

https://msdn.microsoft.com/en-us/library/ms191007.aspx

states that  nondeterministic built-in functions can be used in Transact-SQL user-defined functions and in the list of functions GETDATE is listed.

Can someone please verify which one is true?

Thanks
