No solvers for this yet, After the speed people went thought he public puzzle I mad perhaps i expected too much...

So a hint, about the hint.: the secret key hint is a time/date

And still no one figured out this, so perhaps a bigger hint.

The secret key hint is a value of time.

where would you need a way of expressing time and date an a single number? in computers of course, although this dose lead to the year 2038 problem, but that's twenty years off, why worry about it now :-P
