Viene visualizzata la finestra dei dati a livello di rete.

Le **timestepper.start, timestepper.end** e **timestepper.timestep** è necessario definire le impostazioni che sono le date di inizio e fine dell'orizzonte temporale del modello e la fase temporale in cui il modello verrà eseguito.

Le serie temporali nel nostro set di dati sono mensili, tuttavia eseguiremo il modello in una fase di 1 giorno (1D). Le fasi temporali possono essere in qualsiasi numero di giorni, settimanali (W) e mensili (M).

Si prega di impostare i dati come segue:

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

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

**timestepper.timestep =** D

Fai clic su **Modifica** pulsante, selezionare **Descrittore** per ciascuno degli attributi del time step.

Inserisci i seguenti dati sopra e fai clic **Salva**.

Questo orizzonte temporale può essere più breve dei nostri dati di input, ma le date di inizio e fine devono rientrare nell'intervallo dei tuoi dati. Il formato e la sintassi della data sono rigorosi.

# 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 by asking a question.

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

```
GET https://water-strategy.gitbook.io/waterstrategy/italiano/tutorial/creating-and-running-a-simple-model/creating-and-running-a-model/setting-the-time-horizon.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.
