Hi dude
Welcome to VE. Gr8 to see newer members using the site. If you go to the search function at the top right of the page, you can search on corner pass as there has been a fair amount of discussion on this pass. I would suggest you go through it and then ask questions based on that. In short though, it will take you at least 5 hours to the hut from iNjisuthi and another 6 or so up the pass depending on snow etc. - I would do this over two days.
You would also need to be well equipped with the right gear as snow collects in this pass and sticks around for a while - Check this link out for images of snow in corner pass.
