Also... what is "daka" ? 60 seconds? passcodes that remain valid for two time windows? I've been checking the dictionary and "daka" might mean "minute".
pars minuta prima (first small part) -> minute (1/60th of a circle, or of an hour)
secunda minuta -> second (1/60 of a minute)
minutus -> minute (adj), "very small in size or degree, diminutive or limited, petty"
