This is indeed notabug. It would be illogical to create a time definition that crossed over from one day to the next unless one could also specify the beginning and ending days of the week. This is by-design and is not incorrectly conceived.
Hi utm_kid, the thread you refer to was partly talking about the setup issue you raised, but the part being referred to the development team to fix is the ability to add an end time which is smaller than your start time.
As Ian said, the error the other thread found was that he should have gotten the error message you saw; his attempt to define a start time later than an endtime should not have been allowed.
