In terminal on my PI4 "date" shows correct time.  
In nodered if I inject to a debug and parse the epoch it is also the correct time (UTC+1)  
If I set a specific time in the inject node it outputs an hour late.  
I have recently converted to Docker but am reasonably confident that all the environment stuff is OK.

It is the time zone inside the container that matters (because that is like a VM with its own timezone independent of the host)

Search the forum or WWW, this has been asked and answered a few times e.g:

To check the time zone inside the docker container, use an exec node to run the command `date` and see what it gives.

Note that debug node output can be confusing as it displays using the timezone of the browser.

Thank you both, I get it now. I has set the docker environment variable "TZ=UK" which is wrong and it presumably resorts to UTC. Anyway now sorted.
