Electricity Day Ahead Prices for Home Assistant using Node-Red and Entso-E API

Now, when i modify the url string e.g. as follows (only the relevant parts of url shown)

documentType=A44&in_Domain=10YFI-1--------U&out_Domain=10YFI-1--------U&periodStart=202208172300&periodEnd=202208182200

…and feed that into the browser URL for testing, I get as response an xml like this (just the beginning of the response shown):

<Publication_MarketDocument>
<script/>
<mRID>removed from this</mRID>
<revisionNumber>1</revisionNumber>
<type>A44</type>
<sender_MarketParticipant.mRID codingScheme="A01">10X1001A1001A450</sender_MarketParticipant.mRID>
<sender_MarketParticipant.marketRole.type>A32</sender_MarketParticipant.marketRole.type>
<receiver_MarketParticipant.mRID codingScheme="A01">10X1001A1001A450</receiver_MarketParticipant.mRID>
<receiver_MarketParticipant.marketRole.type>A33</receiver_MarketParticipant.marketRole.type>

<in_Domain.mRID codingScheme="A01">10YFI-1--------U</in_Domain.mRID>

<end>2022-08-18T22:00Z</end>
</timeInterval>
<resolution>PT60M</resolution>
<Point>
<position>1</position>
<price.amount>50.04</price.amount>
</Point>

Pls. pay attention to the lines:

<start>2022-08-17T22:00Z</start>
<end>2022-08-18T22:00Z</end>

In the url it was

periodStart=202208172300&periodEnd=202208182200

If I try to make the query with:

periodStart=202208172200&periodEnd=202208182100

I still get xml response with

<start>2022-08-17T22:00Z</start>
<end>2022-08-18T22:00Z</end>

Exactly the same as in first case. In other words, it does not care whjat i put here as start and end times. It just pushes back what it wants

WTF?
