OH! TIME PERIOD! I thought you mean time zone - time period!
It would depend on the time period. So... if it was in the 1900's (around the time Edward was bitten) it would be different due to how woman were seen and acted in that time. I think that in the past, the female characters would have acted very different to how they do now. If it's in the future, then I haven't the foggest! But if it was in the past, the characters themselves would behave differently.
