DateCreated won't import from .csv

[njenrussell]

Hello. I've imported a variety of tags from a single -csv file for about 1,000 images. Everything has imported perfectly except the IPTC Date Created. Nothing shows up in the field at all. I've tried to navigate my way through the various newbies posts about dates and as a result have tried different tags and I'm pulling my hair out. I really, really don't want to have to update each file individually but I can't figure out what I'm doing wrong.

The data is in the yyyy/mm/dd format but there is no time stamp. Some of the dates are just year (e.g. 1928/00/00), some are year and month (e.g. 1972/05/00) and some of the dates are complete (e.g. 1986/12/11). If there is no known date, it is entered as 0000/00/00.

I've tried running tests on just a few images with changing tags to see if I get different results. Sometimes I get a message that the files have been updated but I still can't see the information in Photoshop. I have even manually entered a couple of dates in the Date Created field in IPTC and then exported the metadata to see what it shows but the field doesn't show up. Clearly I'm missing something. Can anyone enlighten me? Since everything in the .csv imported fine, it seems like it has to be a formatting issue?
