Hi Barry,
I used the 2012.7 coordinates from SkySafari Pro.
By calculation this gives 35m53s.
However, as a cross-check, I obtained the J2000 coordinates from SIMBAD.
This gave the same result 35m53s.
This is not unexpected as most of the change in coordinates will be due to axial precession and relative star positions will essentially be similar.
Using the coordinates given by Stellarium, the result comes to 35m46s, which I assume is probably due to rounding off errors as arcseconds are given in whole numbers for coordinates (of date).
Regards, Rob
