The year before the year 1

[Olson, Arthur David (NIH/NCI)]

One of Paul's documentation changes that I left out of the update was...
	+The year before the year 1 is the year 0, the year before that is
	+the year \-1, and so forth.
If I recall correctly, there's no year zero: the sequence (going backward)
is...
	3 AD, 2 AD, 1 AD, 1 BC, 2 BC, 3 BC...
...or, for "Common Era" fans...
	3 CE, 2 CE, 1 CE, 1 BCE, 2 BCE, 3 BCE..

Have our standard-making friends said anything on the matter?
