If we're on the way to using up the clock, it's a good bet we're breaking the bank:
The national debt clock, as it is known, is a big clock. A spot-check last week showed a readout of 8.3 trillion -- or more precisely 8,310,200,545,702 -- dollars ... and counting.
But it's not big enough.
Sometime in the next two years, the total amount of US government borrowing is going to break through the 10-trillion-dollar mark and, lacking space for the extra digit such a figure would require, the clock is in danger of running itself into obsolescence.
