# How do I configure RFC 3161 timestamp server?

Timestamping can only be configured in the **On-Premises** version of DocuSeal.

To set it up:

1. Go to the **Settings** page.
2. In the right-hand menu, select **E-Signature**.
3. In the **Timeserver URL** field, enter the URL of an RFC 3161-compliant timestamping service. This can be either your own server or a third-party service. For example, you can use [http://timestamp.entrust.net/TSS/RFC3161sha2TS](http://timestamp.entrust.net/TSS/RFC3161sha2TS) or [http://timestamp.digicert.com/](http://timestamp.digicert.com/).
