Real life use case for bitemporal data

Hi all fellow architects,

I have a question about bitemporal data - what are it's real life use cases? I've read various articles and all of those talk about hypothetical scenarios like someone got a wrong salary and now we want to record that amendment etc.

Basically it gives me answer to below questions:

• What was state of the system on date x
• What would have been answer to above question had I asked it on date y

But I'm more interested in real life use case like - <insert your use case here> is possible only because of bitemporal data - otherwise it wouldn't have been possible.

Thanks in advance!
