Hello, everyone.

I have a question about the construction 'it is high time'.

Take the following sentence for example:
It is time that we went home.

If I change the tense of the main clause to simple past, i.e. it was time, is it necessary to change the tense of the subordinate clause?
Which is grammatically correct, 'it was time that we went home' or 'it was time that we had gone home'?

Thanks in advance.
