Timestamp of image upload is missing, unclear documentation on how to add it myself.

Use case: Unable to sort images by upload date client side.

Suggestion: Track upload date server side and include in db, and serve with Image object client side.

Documentation is missing: How to manually add properties to an image server side (transform object during upload)

It is not clear to me if it is appropriate to add properties to a file in the onBeforeUpload hook server side (examples are only explicit about how to call other functions, not about how to transform the file).

Documentation is hard to find: How to manually add properties to an image client side (transform object during upload) (things like user ID, other relevant info) /docs/addFile.md

I looked at the Insert api with onStart, but no example is linked from this page: /wiki/Insert-(Upload). It would be nice if the insert api row where meta is listed referenced via link /docs/addFile.md.

Requests:

1. Can a server side UTC automatic timestamp on upload be added to the lib by default? This is essential, common, expected functionality.
2. Can you tell me how to add this myself (transform an image server side before upload)?
3. Can you document this (more explicitly with an example if it can be done) and in an obvious place? Other libraries usually dedicate a main section of the introduction to transforming objects along with the other major points in the typical pipeline (installation, configuration (storage and options), uploading (from dom/js), retrieving (in dom/js), downloading, transforming, post-processing).

Actually, it would be nice if the main page had those main sections with massive bold titles…

Related Evidence: https://github.com/VeliovGroup/Meteor-Files/issues/459 You can see here another used had this use case, and had trouble determining how to do it. Although the meta object is how to add client-side attributes, and it is not obvious in docs how/when to add things to meta. Also, I would like to add server side UTC timestamps…not client side JS timestamps that may be completely incorrect or faked by a user.

FYI:

onInitiateUpload(file) {
	file.createdOn = new Date().getTime();
},

Have you paid for this software?

1. A user is a customer whether they pay or not (see facebook, instagram, every free product).
2. I donate to projects I use often, and will not ever be supporting this one.

You are welcome to ignore all feedback from all your users, but in the end it will only hurt you. Some individuals just do not take feedback well I suppose, sad to see you become so defensive over your inability to take feedback.
