datetime in template

Thank you for the widget, exactly what I needed..

I get a API response with time H:M:S

Tried datetime to only get hours and minutes but can’t get it to work?

<h3>Avg?ngar fr?n Telefonplan</h5> {subloop-array:Departure:5}<br> {Departure.direction}<br> {Departure.time:datetime,H:i}<br> {/subloop-array:Departure}<br>

Alsp, how to remove parts of the response? I tried to remove everything after first word with: 

Departure:<br>
{subloop-array:Departure:5}<br>
    direction = {Departure.direction|split(" ", 1)}<br>
    time = {Departure.time|date("H:i")}<br>
{/subloop-array:Departure}<br>
serverVersion = {serverVersion}<br>
