How long would it take to listen to all of Haydn's symphonies in one sitting?

Decca has released a 35 CD set of all 107 symphonies (three orchestras participating in the project). The catalogue number is 0 00289 478 9604 3
This link http://www.deccaclassics.com/en/cat/4789604? gives details of the contents of each disc, together with individual running times of each movement. Now if I were an utter b*St*rd, I'd say, here's the list, do the maths. But no, I'm such a good guy, I did it just for you gmackematix, and by my calculation the total playing time is 42 hours 26 minutes and 47 seconds.
