Date code Format changed for HTH Liquid Chlorinator?

Hi all, I picked up some HTH liquid chlorinator gallon bottles at ACE hardware for the first time today (all my nearby walmarts are out of stock of great value bleach), and the date code format doesn't match what is posted on the Chlorine Date Code Decoder/Easy Way to Measure Strength guide.

My best guess is that the first 3 digits are day of year, the next 2 are year, and the last 5 are something else.

Anyone know how to read these? Thanks!

Thanks for your reply, mknauss!

On a side note, these seem like a really good deal at $2.99 a gallon for 10% sodium hypochlorite (walmart is around $2.60 for 6% around here). I wonder if there's some catch, like it containing stabilizer (the HTH website product page says they sell both stabilized and unstabilized versions, but the packaging on the bottles I bought doesn't say if it has CYA in the 90% of 'other ingredients' or not).
