There are some good answers here but I spent some time on this today so figured I'd contribute one more in case it helps someone in the future. Following advice found in other threads I confirmed that, for me, this was indeed caused by a difference in time zone. My django time wasn't incorrect but was set to EST and S3 was set to GMT. In testing, I reverted to django-storages 1.1.5 which did seem to get collectstatic working. Partially due to personal preference, I was unwilling to a) roll back three versions of django-storages and lose any potential bug fixes or b) alter time zones for components of my project for what essentially boils down to a convenience function (albeit an important one).
I wrote a short script to do the same job as collectstatic without the aforementioned alterations. It will need a little modifying for your app but should work for standard cases if it is placed at the app level and 'static_dirs' is replaced with the names of your project's apps. It is run via terminal with 'python whatever_you_call_it.py -e environment_name (set this to your aws bucket).
