Why do we use the past in the sentence “It’s time we got back there.” ?
I would have used the present and I would have said “It’s time we get back there”.
Either one is acceptable. Present tense is saying that the time has arrived to get back there, and past tense is implying that the time to get back there has come and gone. A little more emphatic version would be “It’s past time we got back there.”
