I would guess that date is date of manufacture. Never heard of changing
ceiling tile unless there was a good reason. Many buildings at the university
I worked at had the same tile as when it was built 30 years plus ago. Ask him
for a photo copy of the code showing chapter and verse and if your city has
adopted that code. Call the code compliance office and see how much they laugh.
