According to several sources (see below), you won't get to cast it again. I'm quoting an explanation very fitting from Cranial Insertion:

It won't rebound. Rebound works by replacing the normal process of going to the graveyard after the spell is done resolving with exiling and setting up a delayed trigger. But that never happens with spells that exile themselves, because they do their exiling as part of resolving them. The spell never gets to the point where the game would try to put it into the graveyard, so the rebound never happens.

 

The important thing to understand with both rebound and unearth isn't really where the card is going. What's important is what's putting it there. The rebounded spell doesn't come back because what's putting it in exile is the spell's own exile-it-forever effect. A flickered unearth creature will come back because what's putting it in exile is the flicker's exile-and-bring-it-back effect.

In that sense, it appears that the ruling on Cast Through Time quoted in the question doesn't apply to "zone other than exile", but "zone other than the graveyard".
