# SNTP server settings

**The WIN gateway MUST HAVE a correct date and time to operate.** 

The date and time are obtained from an SNTP server defined in [Network time (SNTP/NTP settings)](/win-gateway-installation-manual/gateway-configuration/network-time-sntp-ntp-settings.md).

If there is no access to an SNTP server, the date shown after power on in Advanced -> Details will be 1970-01-01 and the gateway will not detect any linked or unlinked nodes.

SNTP server access is crucial and is a common cause of WIN gateway mulfunction when it sends no readings.

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

Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:

```
GET https://help.boomerang3.com/win-gateway-installation-manual/quick-installation/win-gateway-setup/sntp-server-settings.md?ask=<question>&goal=<user_goal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case.

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.
