Its actually a bit of a strange question as it asks for the time taken for the liquid to freeze. If you plug theta=0 into the model, it would give the time to "begin freezing" and then the model would not be valid anymore as the liquid cooling assumption would not be valid as it changed state. However, Id guess it means "begins freezing", but it is a bit ambiguous.
