anti Christian bias?

Hi all:

On page 29 of the PostgreSQL User's Guide, distributed with version 7.0.3,
in table 3-8 Postgres Date Input, the last item in the Example column is
January 8, 99 BC. The corresponding Description item reads "Year 99 before
the Common Era". The author or the editor of this manual is obviously
expressing his anti Christian bias in attempting to redefine BC to mean
"Common Era". Throughout history BC, when associated with a date, has
always stood for "Before Christ", and it always will. I challenge the
author/editor to tell us exactly what is the significant event in history
that marks the boundary of what he chooses to call "Common Era".
