HVAC start time local timezone or UTC?

Not sure if this is the right place.
Triggered by the Home Assistant integration, but I assume also applicable for the API.

The optional time to start e.g. HVAC (e.g. 2020-05-01T17:45:00), is that local timezone or UTC?
https://github.com/home-assistant/core/blob/dev/homeassistant/components/renault/services.yaml
And is only that format accepted by the HA integration?
(because: the API mentions it is also allowed to write e.g. "tomorrow at 9am")

Also, can I send multiple start times at once? E.g. 2020-05-01T17:45:00 and 2020-05-02T07:45:00.

I think this API automatically converts it to UTC.
However it is best to make some tests to confirm...
