From the narrations in season 1 and the history books shown, around 100 years ago (specifically, 107 years from chapter 2 of the manga), the first ruler of the Walls, King Fritz the 145th created the walls to protect humanity.
When a someone gains a titan power, their remaining lifespan is set to 13 years due to "Ymir's Curse". Same number of years between the royal family's succesion ritual.
"145th king" means there have been 145 weilders of the Founding Titan at that time. 145 x 13 = 1885. So 107 years ago, it has been 1885 years from Ymir Fritz.
At present time (1885 + 107) it would be 1992 years since Ymir Fritz.
Eren got his titan power at age 10, he's supposed to die when he's 23. Currently, Eren is 15 and has around 8 years left to live.
1992 + 8 = 2000... What was the title of the first episode again? Oh yeah, "To you, in 2000 years." No biggie, nothing to see here.
