NEW YORK (AP) âÄî In a sign of the times, the National Debt Clock in New York City has run out of digits to record the growing figure. As a short-term fix, the digital dollar sign on the billboard-style clock near Times Square has been switched to a figure âÄî the âÄú1âÄôâÄô in $10 trillion. ItâÄôs marking the federal governmentâÄôs current debt at about $10.2 trillion. The Durst Organization says it plans to update the sign next year by adding two digits. That will make it capable of tracking debt up to a quadrillion dollars. The late Manhattan real estate developer Seymour Durst put the sign up in 1989 to call attention to what was then a $2.7 trillion debt.
