2,147,483,647 is the largest 4 byte number that can be held in C++. I know
its not the sameas yr estimate, but it does seem close. If my memory serves
me correctly, and it probably doesn't, if the number of ticks, overflowed
2,147,483,647, it would set the -ve bit and thus one would get an
obscure -ve number.
