DateTime widget shows "T00:00:00.000+01:00" after date, when time_format: false

[Skrubbadubba]

Describe the bug:
This string appears after the date, even though time_format: false. It still works - format is "dd-MM-yyyy", and it saves the field on the actual file with that format.

Expected behaviour:
That string should not be there. Even though it doesn't appear in the file, it will be confusing to users.

Config:

collections:
  - name: nyheter
    label: Nyheter
    label_singular: nyhet
    folder: src/data/nyheter
    create: true
    fields:
     - {label: Rubrik, name: title, widget: string, required: true}
     - {label: Datum, name: date, widget: datetime, time_format: false, format: "dd-MM-yyyy"} 
     - {label: Omslagsbild, name: img, widget: image, required: false}
     - {label: Utdrag, name: excerpt, widget: text, required: true, hint: "Detta är det som står på startsidans nyhetsflöden. Du behöver inte komma på nåt speciellt, copy pastea bara 3 första meningarna från inlägget"}
     - {label: Inlägget, name: body, widget: markdown, required: true}

Nevermind. Adding date_format: dd-MM-yyyy fixes it. Still unexpected behavior to me, but it's not really an issue.

What did you expect should happen?

Where are the docs for the datetime widget unclear?

This is indeed a bug. When time_format is false the time should not show.
