Does the time you see when you clear a floor in Side Order count between lives?

Spent forever clearing that stupid sisyphean floor and when i finally cleared it I got a time of 15:56, but I also died three times so i was wondering if the time just counted the time of the life where i cleared the floor or if it accounted for all three lives because i legit felt like Sisyphus trying to get the boulder up the hill for all eternity
