Cache revalidate modified timezone mismatch

I have a backend returning a last modified header in CEST.

I'm using a 1sec proxy that revalidates as described here:

My problem is that when nginx makes the request to the backend it changes
CEST into GMT, without adjusting the time. Therefore the backend returns a
304 for 1sec + 1 hour, instead of 1sec :(

I tried to do something like set TZ and then start nginx, but this doesn't
seem to make a difference.

export TZ="Europe/Amsterdam"
sudo nginx

What's going on and how can I fix this?
