Marvel Studios' The Marvel Cinematic Universe: An Official Timeline, page 53, firmly places Tony Stark's age as 17 when he became CEO of Stark Industries in 1992, making his birth year 1975.
A Miss Minutes' aside notes the discrepancy between this and previous sources stating he was 21 when he took over the business, and confirms the retcon.
However, the wiki still lists his birth year as 1970 (per older sources) and references him as being 21 when he took over Stark Industries.
This book seems to be the most recent source for the canon timeline, with confirmation of such by Kevin Feige in the foreword, but I'm not sure how it's viewed on this site.
Should Tony Stark's page be edited to reflect this?
