Forum:How do we know the time difference between...

The events of Bridge to the Turnabout...

...And the events shown in the "7 Years Ago" section in Turnabout Succession?

I mean according to the Timeline page, both happened in the year 2019. I know that the 7 years ago part was of course 7 years before the events of Apollo Justice: Ace Attorney, but how do we know that T&T's conclusin and Succession's flashback trial were so close together?
