If we have some actual code date examples we might be able to decipher, mine is DD 111615127126 DJI Phantom 3 Standard, bought 4 months ago. I know a little about code dates but to be sure that I understand the codes correctly I need at least 5 examples like mine.
OK just by comparing the two I'm lost now, usually Julian date is used (i.e. 001=January 1st, 365=December 31st) and usually followed by year which may be four, two or one digit. but there's no relation between the two codes, sorry can't help.
