This happened this year in Bnei Brak, a bakery opened right after Pesach and sold freshly baked bread and Harav Shriel Rosenberg paskened that the buyers violated the issur of חמץ שעבר עליו הפסח.
How can this be? How can you violate the issur of חמץ שעבר עליו הפסח on freshly baked bread after Pesach?
The answer is that the owner of the bakery was in the US for Pesach, and therefore when the bakery baked bread at 10PM the night after Pesach in Israel, it was only 3PM in NY on the 7th day of Pesach. Therefore, the owner of the bakery violated the issur of owning Chametz (since when the bread was baked it was still Pesach for him) and therefore the people who bought the bread violated the issur of חמץ שעבר עליו הפסח.
