Time in report vs time in portal

Hi all,
I am having trouble finding in the ieeg visualization portal the seizures referred to in the reports for data originating from the Hospital of University of Pennsylvania.
In one of the reports (I002_P003_D01) it is explained that time in the portal starts january 1st at midnight, hence if the recording of the patient started the first day eg at 11am, and a seizure happened the first day at 1pm (accoding to report), it should be found on the portal at 2am (2h after the start of the recording in the portal).
However, eg in I002_P003_D01's report, I can't seem to find the information of what time the recording started in real life, and therefore can't find the seizures (which haven't been annotated).
Does anyone have any clue?
Thank you so much for your help.
