You create a transparent magical zone where time flows differently in a 50-foot cube centered on a point of your choice within range. No material, spell or effect can pass into or out of the zone unless it travels through another plane of existence to do so (such as by using the misty step, etherealness, or dimension door spells). Choose one of the following effects for the zone.

Dilated Time. Time passes slower inside the zone so that any creatures inside it experience 10 minutes for every hour that passes outside.  While one round (6 seconds) passes within the zone, 6 rounds (36 seconds) pass outside the zone.

Hyperbolic Time. Time passes faster inside the zone so that any creatures inside it experience 24 hours for every hour that passes outside.  While one round (6 seconds) passes outside the zone, 24 rounds (2 minutes and 24 seconds) passes within the zone.
