Well, I'm sorry Neil, but these things are well documented.

In fact, you can find information on the web, OR you can examine the
man pages in your local installation.

Wait, we're right back where we started... a pair-o-docs....

Ahh yes, as paradoxical as when the Mayan Y2K happened in December of
2012. Gotcha.

Oh, probably. But one of the reasons I use high level languages is so
I don't have to worry about the sizes of integers. In fact, some day,
we won't use floats to store seconds, we'll just use bignum integers
to store some number of Planck times....
