Facebook Timeline's Earliest Date: 1800 Not early enough for Army, Navy, universities By Matt Cantor, Newser User Posted Mar 2, 2012 12:17 PM CST 4 comments Comments In this Sept. 11, 2011 file photo, Facebook CEO Mark Zuckerberg shows Timeline during the f/8 conference in San Francisco. (AP Photo/Paul Sakuma, File) (Newser) – Facebook's Timeline launched for brand pages this week, and Mashable has spotted a problem: It only dates back to 1800. Sure, there aren't too many 212-year-old Facebook users, but the limitation is causing some confusion for institutions that have been around longer—particularly since once they've switched to the Timeline format, they can't switch back. So organizations are finding ways around the problem. The Army, for instance, has placed a note at the earliest position on its Timeline: "At this time, this page only allows us to go back to 1800," it says. "However, we were ‘founded’ in 1775." The Navy has a marker saying "Founded on January 1, 1800," when it was actually born in 1775 as well—a fact that it mentions under the marker. Princeton University's social media boss tweeted his concern: "We go back to 1746 #oops."
