The Neverspill Goblet is designed to hold a fixed amount of liquid, typically around 1 cup of liquid. Anything more than that is not affected by the protection that it offers.
In this case the water would simply overflow if it was generated on the goblet, or if it came from the goblet itself as a specific magic item then it would likely just stop producing any additional water.
The goblet protects only its content, all the other water overflow. And it offers no protection from the disappearance of the created water after 24 hours.
That is neither a ravage of temperature nor time. It is a characteristic of the created water.
