Hjælp til dato fra en amerikansk side importeret som .dat fi

Jeg brug for hjælp til at komme videre med en øvelse som jeg har lavet fra denne bog http://googlemapsbook.com/.

I nedenstående er koderne for hvordan .dat filerne bliver importeret til databasen og det virker ONLINE. Nu er jeg ved at teste det OFFLINE og har problemer med datoen. De fleste data bliver importeret, men p.gra. denne fejl http://www.tinemuller.dk/div/datofejl.gif mangler der nogle.

Jeg har prøvet at ændre "Y-m-d" til "d-m-Y" i linje 20 og 21, men det hjælper ikke. Kan du hjælpe med problemet?
