[Time Travel] How would Wikipedia denote date of death in an article about someone who time-traveled and then died?

I feel like it would be disingenuous to say Kyle Reese (2003 - 1984) or, if Marty McFly died after traveling to the future, 1968-2015.  I'm sure it would also rub a Wikipedia editor the wrong way due to inaccuracy.  What would be the approved method of denoting this?

It would likely state "Kyle Reese (2003 - 1984)" and in the sidebar with more info stating that he died in 1984, aged 26.

If you wanted to expand that in the text body, you could just add the "aged 26" inside the parentheses.
