Random image order in Photostream

I use Aperture to send pictures to shared photostreams so that my family can see the pictures I take of my kids. The photostreams on my iPhone and iPad shows my pictures in the order thay were taken, but in Aperture the images in completly random order. I can't find any way to sort the images in my Aperture photostream, and when I look at the info tab in photostream all images seems to be taken at 00:01 - 01.01.00

Anyone know a fix?
