Describe the issue

files saved in UTC while should be saved in provided timezone

Describe how to replicate the issue

setting filenames to contain time

recordPath: ./recordings/%path/%Y-%m-%d_%H-%M-%S-%f

starting container with timezone set:
```
environment:
  TZ: "Europe/Vilnius"
```
observe filename time is in UTC

Did you attach the server logs?

no

Did you attach a network dump?

no

Solution

installing tzdata inside container fixes the problem for this run

apk update
apk add tzdata

hope image will contain tzdata by default so timezones will work out of the box

Hello, just mount /etc/timezone and /etc/localtime from the host:

docker run --rm -it -v /etc/timezone:/etc/timezone:ro /etc/localtime:/etc/localtime:ro bluenviron/mediamtx

we cannot add tzdata or any other packet to the base image since it's not based on any Operative System, while the -ffmpeg image is based on Alpine and the -rpi image is based on Raspbian.
