We show absolute time in seconds, not moves, because actors can have different speeds (and actions can potentially take different time intervals). We call the time taken by one player move, when walking, a move. Turn and clip are used mostly internally, the former as an absolute time unit. We show distances in steps, because one step, from a tile to another tile, is always 1 meter. We don't call steps tiles, reserving that term for the context of terrain kinds or units of area.
