Image dataset with timestamps? I am starting an exploratory project to determine the time (of day) of which a photo is taken based on image features. I've done some research and downloaded a few databases hoping that "creation date", "last modified", or the file names will properly reflect the time when the original photo was taken, but I have had no luck. 

So far I will be resorting to all of my personal photos, which I do not think will be sufficient enough in quantity or diverse enough in quality.

Are there any natural image datasets out there with timestamps or even timestampped file names?
I found a dataset with EXIF data! It's the MIRFLICKR dataset. I was looking for more amateur-style images, but this is a great start.

I'll post if I make any more findings. Other datasets that I've checked have some images with EXIF data, but they've ranged from 1 in 100 to less than 1 in 1000 images with useful EXIF data.
