showing date and duration of the exposure

[DanVal80]

According to the Android API documentation, when an exposure is detected the time and duration of that exposure is shared with the App. I know this is used for computing the severity of the exposure, but is there any reason why StoppCorona does not provide this information to the users?

Use Case:
I have been notified that I had a contact with a positive person. I am trying to understand when the contact occured. I think it's important: Was I wearing a mask? Were people with me that are not using the app and that I could notify?
If this information is not available, is there any way I can retrieve it? For example, the app tells to stay in quarantine until day X. Can I assume that the contact with the positive person occured at day X-14?
