# Time

The time information is designed to allow you to add information about the date or period of the cultural heritage object represented in your 3D model. You can:

* Enter a **date** or year relevant to the cultural object itself.   (You can add the date when you created your model on the model creation tab).
* Enter a **time period** that is relevant to the cultural object.  Simply click on the period element and scroll the drop down list to select the relevant period.

Once you have finished adding time information, remember to save your changes before moving to the next tab.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://carare.gitbook.io/share-3d-guidelines/user-guide-share3d-dashboard/adding-metadata/time.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
