> Duration of a reservation (endTime - startTime) is specified independently of the recurrence.
This can lead to requests where the duration exceeds the periodicity, for e.g: an hourly reservation
that runs for 2 hours. This will result in multiple concurrently active instances for the
same reservation which is hard both to manage as well as grok. This jira proposes to reject
such requests by clearly informing the user.
