The temperature in a freezer is set to change according to the function \( T(t) = -3|t - 4| + 5 \), where \( T \) is the temperature in degrees Celsius and \( t \) is the time in hours. Find the temperature at 2 hours and determine at what time the temperature will be 0 degrees Celsius. Let's think step by step and output the final answer within \boxed{}.
