bdittmar gave you the "standard" way to proceed in such case, only if what I see is what I think in your copy/paste of command result, I understand you cannot use the timestamp, is that so?
In which case its more based on the directory name itself, which seems to me quite easy:
Ever thought of using it it as an integer,?
Use the highest value and substract 70 ( a quick guess...) giving the reference value: anything smaller be a candidate for removal...

My 2 cents
