If you unzip a file, both created and modified date will be set to the current time.
If you use these fields heavily in your vault and want to prevent this from happening, I recommend having a manual field for `Created`.
You can just add the file in [[Templater Snippets#Today Timestamp]]
For existing notes, using [[Obsidian Linter]] you can add it based on the current `Created` attribute, so when you do unzip you can use `Created` as your source of truth. Just be sure to disable it once or else when it lints your files it will just use the corrupted unzip date 💀
