Bug description:  GregorianToJD function returns incorrect values

The GregorianToJD Calender function returns incorrect 
results. As far as I can tell, this applies to the 
GregorianToSdn internal function in the PHP source.

There's not really any point putting a sample PHP script 
here, as it's the algorithm that seems to be at fault. I 
took two specific cases and worked through the 
algorithm by hand (i.e. pen and paper). Here are the 
results:

2nd February 2001 (2/2/2001) = 2451943
7th June 1980 (7/6/1980) = 2473618

As I understand it, the Julian Day Count is a uniform 
count of days from some time around 4714 BC. Now, 
how can 2/2/01 be a lesser number of days than 
7/6/80?

I have no idea what the correct results for these test 
cases are, nor any idea what particular part of the 
algorithm is wrong. It's just wrong somewhere!
