# Set Note Created At

`PATCH /v2/notes/{note_id}/created-at`

Set a note's visible creation timestamp without changing its content.
The supplied `created_at` must include a timezone offset and cannot be in the future.
It can only backdate the note: the timestamp cannot be later than
when the note was originally created.
This operation changes note metadata only.
Trashed notes must be restored before their creation date can be changed.

## Path parameters

- `note_id` string, uuid, required — UUID of the note whose visible creation timestamp should change. The caller must own this note.

## Request body

- SetNoteCreatedAtRequestSchema
  - `created_at` string, date-time, required — New visible creation timestamp for the note (ISO 8601). It must include a timezone offset and cannot be in the future. It can only backdate the note: the timestamp cannot be later than when the note was originally created. This changes note metadata only; it does not update note content.
