Namron - Adjust time/date of heated floor thermostat from Homey?

Just noticed all of my Namron heated floor thermostats (4512744/45) had the wrong time and date. I was expecting Homey Pro and its Namron app to automatically adjust time and date as needed for daylight savings changes, power issues etc. Is this a missing feature of Homey Pro or its Namron app?

I have the same issue. Just set the correct time a couple of days ago and now I see that it is a few min off.
