[defect]: Can't set timezone properly using official docker image

[masscream]

What type of defect/bug is this?

Unexpected behaviour (obvious or verified by project member)

How can the issue be reproduced?

Simply run the server and make some auth attempts, it does not matter if successful or not, more that matters is, if it prints the attempt time into the log.
Check the log, the event times are not correct (depending on your timezone, mine is Europe/Prague).

Tried:

• docker variable -e TZ=Europe/Prague
• mounting /etc/timezone to the container with the correct TZ

both did not work

The whole container as I use it.

docker run \
  -d \
  -t \
  --net bridge \
  --ip 10.0.10.9 \
  --name freeradius \
  --restart always \
  -p 1812-1813:1812-1813/udp \
  -v /media/AppData/volumes/freeradius_volume/_data/etc-freeradius:/etc/freeradius \
  -v /media/AppData/volumes/freeradius_volume/_data/var-log-freeradius:/var/log/freeradius \
  -v /media/AppData/Temp:/tmp \
freeradius/freeradius-server

Docker images default to UTC.

Yes, this is the first thing I tried, by setting the -e TZ=Europe/Prague. Even with this variable, the time is still in UTC. For other containers, this works smoothly.
