The video says the receipt stamped @ 5 pm.
I think the video misspeaks. The text copy says she was there about 5 hour prior to putting her down for the night, which was 7:30. The voice video says both it was purchased at 5, and then goes on to say 5 hours before police say she put the baby down for the night.
They're in conflict - my guess is, it was 2:30 p.m.
