Actually, I wouldn't draw that conclusion quite so quickly. I'm sure you're aware of the fact that different time periods aren't the only discrepancy among the people here, but that a large portion are also drawn from different worlds entirely. I'd even go so far as to say the majority of Marina's inhabitants don't share the same world and with that most points of reference become irrelevant.
Judging by your appearance alone I'd wager a guess and say we're not from the same world. With that in mind it's just as likely that you do have similar methods to the ones I'm used to as it is that you don't.
