Is it possible to change a tweet's timestamp (via web-UI or API) after you've created ("tweeted") a tweet? Is the timestamping out of the user's reach?
I am looking for "one way web apps", Internet applications that allow you to post, but not to change what you've posted afterwards. I think Twitter is one of these web apps. It only offers delete, but not to modify tweets, once published.
I am asking in relation to researching "digital forgetting", so I am open for more suggestions of similar one way apps.
To clarify my purpose:
The idea of having "one way web apps" is similar to the idea of the bitcoin "block chain", where each new block contains a hash of the previous block, so you can't change what's in a chain's "tail" when a new "head" is added. And then, it's also public, so everyone is watching the integrity of the chain. I think it's also called forward hashing, a principle found in modern DVCS. That's why the bitcoin block chain is sometimes used to store non-bitcoin related hashes and this way providing proof of a certain hash at a certain point in time. A bit like buying today's newspaper and taking a photograph of it with something else.
Twitter, as it's immutable (discussed here) is similar, although the company "guarantees" for the integrity, with a closed sort-of forward hashing system, as they don't allow users to alter tweets - but then the public is watching which levels this.
