Home Assistant Integration (Emoncms) wrong Graph Time, correct LastUpdated Time

Hi,

I added Emoncms to Home Assistant with the Emoncms - Home Assistant Integration.

I created a Feed and imported Test Data. The Last Import was with the Timestamp 1744638590 and value 300.

Home Assistant synced the change and in the Home Assistant Feed Atribute i can see the correct timestamp under LastUpdated but the Graph show 15:50:25 for the change not 15:49:50.

Screenshot is attached did I miss something here ?

Thx
