Actually, I think (hope) that the problem can be fixed at the AAVSO end. 
The problem is that CCDSoft reports the time at the beginning of the 
exposure instead of the middle. All past CCDSoft observations in the 
International Database will have to be corrected by adding 1/2 the 
exposure time to the archived times.
