A janela de dados no nível da rede é exibida.

O **timestepper.start, timestepper.end** e **timestepper.timestep** as configurações precisam ser definidas, quais são as datas de início e término do horizonte de tempo do modelo e a etapa de tempo na qual o modelo será executado.

A série temporal em nosso conjunto de dados é mensal, mas executaremos o modelo em uma etapa de 1 dia (1D). Os intervalos de tempo podem ser em qualquer número de dias, semanais (W) e mensais (M).

Defina os dados da seguinte forma:

**timestepper.end** = 2021-12-01

**timestepper.start =** 2020-01-01

**timestepper.timestep =** D

Clique no **Editar** botão, selecione **Descritor** para cada um dos atributos da etapa de tempo.

Insira os seguintes dados acima e clique em **Salvar**.

Esse horizonte de tempo pode ser menor do que nossos dados de entrada, mas as datas de início e término devem estar dentro do intervalo de seus dados. O formato e a sintaxe da data são rígidos.

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## 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://water-strategy.gitbook.io/waterstrategy/portugues/tutoriais/creating-and-running-a-simple-model/creating-and-running-a-model/setting-the-time-horizon.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.
