Subject: [PATCH] Proposes adding tzdata to Dockerfile so that container will
respect TZ= environment variable.
Example docker-compose.yml
```
version: '3.6'
services:
adguardhome:
container_name: adguardhome
image: adguard/adguardhome
restart: unless-stopped
environment:
- TZ=Australia/Sydney
ports:
- "53:53/tcp"
- "53:53/udp"
- "8089:8089/tcp"
- "3001:3000/tcp"
volumes:
- ./volumes/adguardhome/workdir:/opt/adguardhome/work
- ./volumes/adguardhome/confdir:/opt/adguardhome/conf
```
Start container:
```
$ docker-compose up -d adguardhome
Creating adguardhome ... done
```
Test 1: shows container ignoring TZ== and running UTC.
```
$ docker exec adguardhome date
Wed Mar 31 11:05:37 UTC 2021
```
Add tzdata package to container:
```
$ docker exec adguardhome apk add --no-cache tzdata
fetch http://dl-cdn.alpinelinux.org/alpine/v3.12/main/armv7/APKINDEX.tar.gz
fetch http://dl-cdn.alpinelinux.org/alpine/v3.12/community/armv7/APKINDEX.tar.gz
(1/1) Installing tzdata (2021a-r0)
Executing busybox-1.31.1-r19.trigger
OK: 8 MiB in 17 packages
```
Test 2: shows container respecting TZ= and running UTC+11.
```
$ docker exec adguardhome date
Wed Mar 31 22:07:58 AEDT 2021
```
