Is there any difference? Which would be better to describe a requirement for 1 or 2 days. Suppose I need to inform my Operations team, that I need a particular requirement to be implemented but I want it only for a day or two?
From ODO I get:
Temporary: Lasting for only a limited period of time; not permanent.
Momentary: Lasting for a very short time; brief.
So both seem to have the same meaning. Which one would be appropriate here.
Statement 1: My team's requirement for implementing ABC system is temporary.
Statement 2: My team's requirement for implementing ABC system is momentary.
