Axis of Eternity (Chronomancy School of Magic)

From you hand you blow the dust of a celestial’s bones, which becomes a whirling globe of crackling light in a 15-foot radius around you. Inside the globe, time does not exist. It is immobile and lasts for the duration. Creatures within the globe do not age, are immune to poison damage and the poisoned condition, cannot take levels of exhaustion, and do not need to sleep, eat, or breathe. They cannot benefit from a short or long rest while inside the globe.
From inside, creatures can see into the present time, watching events transpire there. If any creature enters or exits the globe, the spell ends.

At Higher Levels. When you cast this spell at 9th level, the duration becomes 1 month.
