Reason you're getting this behavior is because when you execute following line of code:

CloudBlockBlob blockBlob = container.GetBlockBlobReference(blob.ToString());

It essentially creates a new instance of CloudBlockBlob object and it's properties are initialized to the default value. You would need to call FetchAttributes method on this to fill the properties.

Also, when you list the blobs the properties of the blob are fetched as well. So you need not create a new instance of CloudBlockBlob. Simply use the blob object you got as listing result and use the properties from there. So your code would be:

        foreach (var blob in blobs)
        {
            var timemodified = blob.Properties.LastModified;
        }
