Just checked, I did it in 2015. 14hrs27m. This is me at the top of the last climb. I was fucked. Like, proper fucked. And ended up doing most of the descent and run into Meiringen on the dark with a tiny flashing front light.
It didn't help that I got seriously dehydrated racing to Airolo to beat the cut off time for the Platinum route, and couldn't eat solid food for the second half of the ride.
