How do I fill in the input type= "time" field in Thymeleaf?

Question

The Spring-Boot + Thymeleaf project does not fill in the input type= "time" field When opening the html form. That's how it works:

<input type="time" class="form-control" id="inputTime" th:value=${CarEntity.timeOperation} required>

And here it is:

<input type="time" class="form-control" id="inputTime" th:field="*{timeOperation}" required>

Or so:

<input type="time" class="form-control" id="inputTime" th:field="*{timeOperation}" th:value=${CarEntity.timeOperation} required>

The field remains empty. And if I use <input type= " text> then everything works fine.

<form id="f-pr-03" th:method="POST" th:action="@{/edit/{id}(id=${carEntity.getId()})}" th:object="${carEntity}">
That's how everything works and displays and reads.
    <label for="inputName">Input name</label>
    <input type="text" class="form-control" id="inputName" th:field="*{name}" required>

But this is not displayed
    <label for="inputPTTime">Input time</label>
    <input type="time" class="form-control" id="inputPTTime" th:field="*{timeOperation}" max="17:50" min="00:01" required>

And this is how it is displayed, but not transmitted by the POST method 
    <label for="inputPTTime">Input time</label>
    <input type="time" class="form-control" id="inputPTTime" th:value=${CarEntity.timeOperation} max="17:50" min="00:01" required>
    <button type="submit" name="action">Save</button>
</form>

I don't if it is still relevant since it's benn a while. Thymeleaf provides a special attribute th:field responsible for binding input fields with a property in the bean class. This attribute behaves differently depending on whether it is attached to. Thymeleaf supports all-new input types introduced in HTML5 such as type="color" or type="datetime".
