Homey should use NTP to query remote servers for the correct time, but it looks like that’s not working for your Homey.
Do you have some sort of firewall active that might be blocking requests to any of these servers:
0.debian.pool.ntp.org 1.debian.pool.ntp.org 2.debian.pool.ntp.org 3.debian.pool.ntp.org
Thanks for the suggestion.
No blocking of any kind in the network. Is this different compared to Homey 2019?.. that device worked perfectly ever since 2019… 
The 2019 probably uses a different Linux distribution.
Perhaps you should contact Athom about this, because not only is your Homey’s internal clock not set to UTC, it’s also not synced.
Thanks, I just raised a ticket at Athom.
Not sure if you tried to move the location pointer already?:
This ‘forces’ Homey to set the correct timezone and time
