Bug with freeNas (freeBSD) and apscheduler

[0xE0-rng]

When running Premiumizer on freeNas 9.10 it crashes with the following stack trace:

Traceback (most recent call last):

ValueError: Unable to determine the name of the local timezone -- you must explicitly specify the name of the local timezone. Please
 refrain from using timezones like EST to prevent problems with daylight saving time. Instead, use a locale based timezone name (suc
h as Europe/Helsinki).`

This looks like an apscheduler bug but i am not sure.

Update:
Ok i found the reason, its a problem with tzlocal. Its unable to read the correct time zone on freeBSD systems.
There is a pull request here but it has not been accepted yet.

I tested the pull request mentiond above and everything works great on freeBSD now

i also met this problem;
solve:
sched = BlockingScheduler(timezone="UTC")

You can also set up the timezone without changing the code.

I did two things, not sure which one worked but both are quick.

1. Set up your timezone as a system var:
   export TZ=America/Los_Angeles
2. Change the zonefile as described here: https://www.cyberciti.biz/faq/howto-set-date-and-time-timezone-in-freebsd/

For freebsd its not export, but rater setenv.
This error can be fixed by running e.g. setenv TZ Europe/Berlin
