```

##### ADDITIONAL INFO
I confirmed both locally and through SSH that I can use tzuil /s "Eastern Standard Time_dstoff" and the change is accepted. Only through ansible does it not accept the timezone change.

There is also no issue changing timezone for non-dstoff timezones:

```

```

Working around the issue for now with:
```
- name: Set TimeZone
  win_command: 'tzutil /s "Eastern Standard Time_dstoff"'
```
needs to be installed to be able to run this module.
