# How to change the date format in the GenomeStudio Final Report in the Processing Date Field
GenomeStudio users might be interested in changing the date format in the Final Report but are unable to find any option in GenomeStudio. This is because the GenomeStudio software does not provide any option to change time/date settings.
The date and time settings displayed in the Final Report are **based on Operation Sytem (OS) settings**. Some users might change the date and time settings but still experience that the changes made to the OS settings are not displayed in the Final Report (Figure 1). This is because the **GenomeStudio software operates in English (US)**, therefore, the Region and language settings would have to be set to English (US) on the computer as well.
For instructions on how to create a Final Report, review the paragraph “**Generate a Final Report**” in the [**GenomeStudio Genotyping Module v2.0 User Guide**](https://support.illumina.com/downloads/genomestudio-2-0-user-guides.html) or [How to generate a Final Report and export a Data Table in GenomeStudio 2011.1 Methylation Module](/microarray/general/microarray-general-reference_material-list/000008282.md).

## 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://knowledge.illumina.com/microarray/general/microarray-general-reference_material-list/000005246.md?ask=&goal=
```
`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.
