        <pre>While Safari reports support for the input type &quot;time&quot; form field and the step-attribute, the step-attribute’s behaviour is not reflected in the user interface.
According to the specification of the time type for the input element, the step-attribute allows developers to preset iteration-steps for valid values. This is implemented by Chrome as per specification, only showing hours and minutes when the steps attributes only allows minute-steps and also reflected in only allowing to increase/decrease or enter valid steps into the field.

Safari should comply with the specification here and provide users proper step-attribute support.

A demo is here, you can use Chrome to see the correct[1] implementation and Safari to see the current Safari implementation: <a href="https://jsbin.com/burewigije/edit?html,output">https://jsbin.com/burewigije/edit?html,output</a>.

----
[1] Addendum: Chrome reports the fields value as 8:00 instead of 8:00:00 if steps is set to a value &gt; 60, which is wrong.</pre>
