We have a similar report from the lounge at JFK where entry was denied due to an after-midnight departure. I doubt this literal interpretation is what American Express management intends, but it will take several complaints to make them aware of how the rule is being implemented.
I can't remember if I posted it in this thread from a trip last year. Either OP is unlucky or I got really lucky, but I was able to enter DEN Centurion Lounge in a similar situation.
