I ran your numbers through Voyager. While they didn't perfectly line up, the "close enough" figures placed the sun at those coordinates at roughly 10:00 UTC. I ran into the same problem you did UNTIL I remembered to switch the coordinates to ecliptic rather than local horizon. As soon as I did that, the value of 70° 22' (okay, actually 21' 38.2" to get nitpicky) popped into place.
Hope that helps. Sorry for the delay, I don't check these forums quite so often.
Best regards and clear skies!
