Simple Q&A by RAW for Pathfinder 4

Q25: If a Psion uses the Genesis power and on a second manifestation augments to change planar traits and makes it have the Timeless trait, is the duration of first Genesis itself also treated as permanent?

On planes with this trait, time still passes, but the effects of time are diminished. How the timeless trait affects certain activities or conditions such as hunger, thirst, aging, the effects of poison, and healing varies from plane to plane. The danger of a timeless plane is that once an individual leaves such a plane for one where time flows normally, conditions such as hunger and aging occur retroactively. If a plane is timeless with respect to magic, any spell cast with a noninstantaneous duration is permanent until dispelled.
