DynamoDB or other databases like PostgreSQL. To answer the original question: If you need such capabilities AWS recommends that you create the metadata database yourself using e.g. So if you want to know the newest file you have to query all files under given key, check each file metadata and sort. S3 doesn't create a metadata database of your bucket that could be queried for the files between given timestamp ranges and stores the LastModifiedTimestamp in metadata associated to each object separately. Each file is universally identified by a single HASH (bucket_name + key) and the retrieval is always O(n) and that's the primary function of object storage service - to store "inifinite" number of files that you can always instantly retrieve assuming you know the hash. Usually object storages do not have metadata databases for stored files. I guess that the problem is not the limitation of awscli but the nature of S3 which is an object storage service.

The combination of leaving this basic feature out and billing for file listings is highly suspect. You're right, sorry for my lame reply and I agree this sort of functionality would be very helpful in aws-cli.
