I have the exact same problem, the meta data “date taken” is ignored and the upload date is used instead, obviously this causes problems with sorting the gallery by date taken!!

PS I am running Nextgen Gallery 2.0.40 and WordPress 3.8!!
Bug report submitted, thanks
I also have the same problem since updating to 1.9.12, it appears that older images are having their dates changed and new ones are getting 1 Jan 1970 even though their metadata is correct. Any ideas anyone?

Andy
