There's no mention of time travel.
The Last Titan
"In the expansion we will return to Ulduar and witness the return of the Titans to Azeroth. We will cover a vast conspiracy, which will stretch throughout the history of the world. It will challenge everything you think you know. Titans and the intentions and the true nature of Azeroth itself."
Again... still no mention of time travel whats so ever.
