[defect]: Can't set timezone properly using official docker image, tzdata package missing

[masscream]

What type of defect/bug is this?

Crash or memory corruption (segv, abort, etc...)

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

what helped was installing additional package for TZ support. Timezone functionality belongs to basic functions nowadays, please include the package in the official version.
