Tries to bring standardization into social media posts' date-time values.
Why 1? Working with standard timezones (such as UTC) is useful when cross-referencing dates from distinct online platforms.
Why 2? Some platforms actively hide the real date/time of a post (eg: tiktok, youtube, ...).
This extension converts and decodes, where possible, complete upload/post date-time values into standard timezones (like UTC or your machine's local timezone) and allows the conversion to any other timezone, besides exporting/copying all values.
Install on brave/chrome.

| Platform | Status | inspired by |
|---|---|---|
| Twitter/X | ✅ | |
| Tiktok | ✅* | tiktok-timestamp |
| Discord | ✅* | |
| ✅ | ||
| Bluesky | ✅* | works only for english translation of the platform, hard to expand |
| TODO | come help! Linkedin-post-timestamp-extractor | |
| Youtube | TODO | come help! it requires the official API (see amnesty youtube dataviewer) / and possibly file metadata |

How to use?
Timestamps handled by this script:
* Individual /video/ pages -> hover over username
* User page video thumbnails -> hover over username/date
* /explore feed page -> hover over username/date
* /foryou feed page -> hover over username/date
*. Also works on tiktoks archived on web.archive.org.
Timestamps not handled by this script:
* "you may like" thumbnails -> is it possible to do it for the "you may like" section on the right side of a video page? there is no id in the html but perhaps the click event listener could somehow be intercepted/mocked.
Timestamps not handled by this script: 1. video thumbnails on the right pane AKA "You may like". (can you find a way to do it?)

git clone https://github.com/my-username/my-awesome-extension/npm install to install all required dependenciesnpm run buildThe build step will create the distribution folder, this folder will contain the generated extension.
(optional) Using web-ext is recommended for automatic reloading and running in a dedicated browser instance. Alternatively you can load the extension manually (see below).
npm run watch to watch for file changes and build continuouslynpm install --global web-ext (only only for the first time)web-ext run -t chromiumTo add a new fixer you need:
1. edit manifest.json content_scripts and web_accessible_resources to include wildcards for the platform and reference a new content-script file
2. JS logic in the content-script file: see the example for twitter. Feel free to add additional CSS if needed.
3. If the platform is archivable on archive.org try to add your fixer there as well (see the example for twitter in manifest.json)
4. Test and make a PR with screenshots/notes on implementation if needed
It's possible to automatically publish to both the Chrome Web Store and Mozilla Addons at once by adding these secrets on GitHub Actions:
CLIENT_ID, CLIENT_SECRET, and REFRESH_TOKEN from [Google APIs][link-cws-keys].WEB_EXT_API_KEY, and WEB_EXT_API_SECRET from [AMO][link-amo-keys].Also include EXTENSION_ID in the secrets (how to find it) and add Mozilla’s gecko.id to manifest.json.
The GitHub Actions workflow will:
19.6.16 and sets it in the manifest.jsonThanks to the included GitHub Action Workflows, if you set up those secrets in the repo's Settings, the deployment will automatically happen:
