Suggestion: Help me in function `_get_localzone` to get timezone data

[wowopo]

There has some unknow reason on this file /etc/timezone is empty, but right now the function _get_localzone first to parser this file to obtain time zone info, in this case has raise UnknownTimeZoneError.

But I saw this function has other way to get Timezone info, so we can change this func to raise error when return without Timezone. Sorry for my bad English.

  File "/usr/local/ba/run.py", line 2, in <module>
    from app import app
  File "/usr/local/ba/app/__init__.py", line 50, in <module>
    scheduler = APScheduler()
  File "/usr/local/lib/python3.7/site-packages/flask_apscheduler/scheduler.py", line 36, in __init__
    self._scheduler = scheduler or BackgroundScheduler()
  File "/usr/local/lib/python3.7/site-packages/apscheduler/schedulers/base.py", line 87, in __init__
    self.configure(gconfig, **options)
  File "/usr/local/lib/python3.7/site-packages/apscheduler/schedulers/base.py", line 126, in configure
    self._configure(config)
  File "/usr/local/lib/python3.7/site-packages/apscheduler/schedulers/background.py", line 29, in _configure
    super(BackgroundScheduler, self)._configure(config)
  File "/usr/local/lib/python3.7/site-packages/apscheduler/schedulers/base.py", line 697, in _configure
    self.timezone = astimezone(config.pop('timezone', None)) or get_localzone()
  File "/usr/local/lib/python3.7/site-packages/tzlocal/unix.py", line 131, in get_localzone
    _cache_tz = _get_localzone()
  File "/usr/local/lib/python3.7/site-packages/tzlocal/unix.py", line 70, in _get_localzone
    return pytz.timezone(etctz.replace(' ', '_'))
  File "/usr/local/lib/python3.7/site-packages/pytz/__init__.py", line 181, in timezone
    raise UnknownTimeZoneError(zone)
pytz.exceptions.UnknownTimeZoneError: ''

Well, the easiest is to just delete /etc/timezone, or edit it, and add the correct timezone.

tzlocal is trying to find your timezone in the systems configuration. If it's incorrectly configured, tzlocal will fail in doing so.
