# Loading timestamp root certificate

<mark style="color:red;">**This only applies to documents signed on 11 and 12 June 2025**</mark>

The timestamp certificate proves that your document was signed at the stated time. In order to verify that the timestamp certificate in your downloaded document is valid, you might need to load in the timestamp root certificate.

To load it in, please follow the steps below:

1. Download the GlobalSign root certificate from [here](https://secure.globalsign.net/cacert/root-r6.crt).

   1. If you're unable to access that link, please visit [GlobalSign's CA repository](https://support.globalsign.com/ca-certificates/root-certificates/globalsign-root-certificates) and download the **R6 GlobalSign Root Certificate.**

## 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://guide.signify.gov.sg/user-guides/certificate-guide/loading-timestamp-root-certificate.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.
