Times doesn't exist in the game.
A clock wouldn't mean anything.
Time certainly does exist, it is just that nothing really is dependent on it.
Open your journal and hit the middle icon for dialogue between the quest and tutorial icons. It shows the day and time of each npc you talk to through out the day. The weird part is that resting doesn't actually advance the day at all. If you talk to an npc then hit end day and sleep and immediately talk to another npc as soon as you warp back to where you were you'll see the dialogue shows that only minutes have passed and it is still the same day as before.
