Is there an error in the documentation example for the ADDTODATE function in MATLAB?

The example in the documentation for the ADDTODATE function states that the following command:

R = addtodate(datenum('12/24/1984 12:45'), 20, 'day');

datestr(R)

should return the following result:

 ans =

   13-Jan-1999 12:45

However, when I execute the above example, I obtain a different result:

 ans =

   13-Jan-1985 12:45:00

This change has been incorporated into the documentation in Release 14 Service Pack 3 (R14SP3). For previous releases, read below for any additional information:

This has been verified as an error in the documentation for the ADDTODATE function within MATLAB. The documentation should read as follows:

"Adding 20 days to the given date in late December causes the calendar to roll over to January of the next year: "

R = addtodate(datenum('12/24/1984 12:45'), 20, 'day');

datestr(R)

 ans =

   13-Jan-1985 12:45:00
