My controller died at 1:34:38, but I stopped moving at 1:34:43. I reconnected and started moving at 1:35:05, so I subtracted those 22 seconds off my final time :]

Start Time: 01:15:00 End Time: 02:02:06 Time before 22 seconds off: 47:06 Official Time: 46:44

Edit : Be careful with your controller next time ;-) Méléagant.
