Date Range not returning correct TIME in Twig; end_value not returning anything

Problem/Motivation

Using twig inside a view in order to get the time of a DateTime Range field like:
{% set myStartTime = field_event_start.value|date("H:i:s", "UTC") %}
does return the time of now() instead the time of the field_event_start.

While {% set myStartDate = field_event_zeitpunkt.value|date("Y-m-d", "UTC") %} gives the correct date of the field.

end_value: {% set myStartDate = field_event_zeitpunkt.end_value|date("Y-m-d", "UTC") %} does not return anything at all.
