Hi, I am not the author of the related codes but I am interesting in reading source codes.
According to my understanding, the reason behind the -1 design was defined in org.dspace.content.DCDate, where -1 means undefined value for year, month, day, hours, minutes and seconds. DCDate is based on Calendar class of java. 0 is not a good choice to represent undefined value because 0 is a valid value in java.util.Calendar for y,M,d,h,m,s. (e.g. 0 means January when it is a month value). In dspace usage, when there is only year value with no month and day, submitters can just put in the year value (e.g. 1930) then sorting will be done correctly. Cheers, Allen.
