Quasi-Eternal Rest (3.5e Spell)

You touch the target lightly on the forehead, and they fall asleep.

When you cast this spell, specify an event that could be observed by the creature in question, were they not frozen in time.

If the touched creature fails their Will save, they are put into a state of suspended animation as per temporal stasis. When the specified event occurs, the creature is released from that state of suspended animation.
