If you think the national debt is bad, the people who own the National Debt Clock are even more pessimistic: They’re planning on reformatting their Times Square-area ticker so it can keep track of a debt 100 times bigger than the current $10 trillion.

With the national debt now at $10.1 trillion, the late Seymour Durst’s legendary National Debt Clock has run out of space. To fix it, the Durst Organization plans to add places for two extra digits next year, a spokesman said.

By tomorrow, the digital dollar sign now on the clock will be switched to a number one – the “1” in $10 trillion – until the sign can be redone.

Durst, who died in 1995, put the sign up in 1989 to call attention to the burgeoning national debt. But less than a decade ago, the clock itself was turned off when the national debt decreased.
