In Jain cosmology, time in hells is not the same as time on Earth.

• Hell time is extremely prolonged compared to Earth time.
• A being in naraka experiences suffering for a very long karmic duration, and the passage of time there is described as vastly different from human time.
• The exact comparison varies by the level of hell and by the particular karmic lifespan of the soul.
• So, in Jain Dharma, there is no single fixed Earth-to-hell time conversion for all hells.

In simple words: one moment on Earth can correspond to a much longer experienced period in hell realms, depending on the state and level of existence.

If you want, I can also explain the 7 hells in Jainism and their time/life-span differences.
