Power Rangers: Season 5, Episode 25

5 - 25: When Time Freezes Over (3)

Divatox's attempts to launch a freeze key into the sun and cut the planet off from it's heat are hampered by the Rangers, so she enlists the aid of the Clockster monster to turn back time so she can save the freeze key and activate it elsewhere, but her scheme backfires when a curious Clockster touches the key and Earth's entire timeline is frozen.
