That's not true if faster than light travel is possible (e.g. wormholes, warpdrives, any form of time travel, etc.) And even so, it doesn't make a lot of sense to redefine time that way. It would be like a pre-electricity civilization declaring that things outside their mail-cone (how fast mail can travel) haven't actually happened yet.
