Answer:
Ser
Explanation:
When talking about time in Spanish, you think you would use estar because it is a state. However, the answer is ser because it is talking about something characteristic of the current moment, the time. This seems a bit counter-intuitive but it is one of the only rare exceptions, so no need to worry.
Have a wonderful day! :D
