it's time I told vs it's time I tell

"I think it's time I tell you what I tell my family."

"I think it's time I told you what I told my family."

"I think it's time I told you what I tell my family."

"I think it's time I tell you what I told my family."

Each sentence can describe a distinct case.

But in this case, I like the topmost one, the original. "What I tell my family" implies that a conversation is ongoing, and choosing to address all Californians in the same manner is just good old-fashioned people-politics in a time of crisis.
