It's possible that the term is being used in a specific context or within a particular research field. If you could provide more context about where you encountered this term, I might be able to help you understand its meaning.
For example, tell me:
* Where did you see this term? (e.g., a research paper, a website, a conversation)
* What was the context? (e.g., what was the topic being discussed?)
With more information, I can try to determine what "liver oxidation time" might refer to and provide a better answer.
