Your question is a little vague. Two currents would imply only two current carrying conductors, whereas the standard 460 volt power system is derived a 3 phase generator. It is possible, however, to power some types of equipment from only two phases or even a single phase along with the neutral conductor.
To determine how many years ago 460 BC was from the current year, you subtract 460 from the current year. Current year - 460 BC = 2024 - (-460) = 2484 years ago So, 460 BC was approximately 2484 years ago.
