Android Police says this on the matter:
"After digging through the AOSP source, I think the bug can be likely found in one of these commits, probably in the datepicker/DatePicker.java file - if you spot it, definitely drop a note in the comments. I think it has to do with adjusting for indexes that start with 0 - "off by 1" bugs are quite common."
