US debt clock runs out of digits

[Robert]

The US government's debts have ballooned so badly the National Debt Clock in New York has run out of digits to record the spiralling figure.
The digital counter marks the national debt level, but when that passed the $10 trillion point last month, the sign could not display the full amount.

An achievement of sorts, I suppose.
