# Time zones

Each dataset has its own time zone. LeadBoxer uses it to show dates and times for that dataset and to decide what periods such as "Today" or "Last 7 days" mean when you filter leads and accounts. The default is Europe/Amsterdam.

Set the time zone to where your team works, or where most of your visitors are, so that "today" in LeadBoxer matches your working day.

## How to change a dataset's time zone

1. Open **Settings** in the left menu.
2. Go to **TimeZones** (Manage Dataset Timezones).
3. Every dataset you have access to is listed by name. Pick the time zone for each one from the drop-down.
4. Click **Save**.

{% hint style="info" %}
Using the [API](/leadboxer/platform-and-api/developer-portal.md)? Pass the `timeZone` parameter (for example `Europe/London`) to control how time filters are evaluated in API results.
{% endhint %}

# Agent Instructions

## 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.leadboxer.com/leadboxer/using-the-app/elements/timezones.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.
