Hello,

I believe I found a bug in Microsoft's implimentation of COleDateTime. I am working on an astronomical calculator and obviously one can enter celestial events for any year. The error appears to come from the omission of the Julian to Gregorian calendar change which is generally considered to have been adopted in 1582. For example October 4, 1582 a Thursday was followed by October 15, 1582 a Friday. Microsoft gets 10/15/1582 correct, but misses any date earlier than this. Also, any other time functions using dates earlier than this are incorrect. Any thoughts?

thanks,
mitch
