tzlocal 3.0b1 breaks apscheduler

unleash-client-python depends on apscheduler==3.6.3: https://github.com/Unleash/unleash-client-python/blob/master/setup.py#L24

apscheduler depends on tzlocal >= 1.2: https://github.com/agronholm/apscheduler/blob/master/setup.cfg#L27

Installing unleash-client-python gets us tzlocal 3.0b1 through apscheduler. tzlocal 3.0b1 breaks the compatibility:

  File "/usr/local/lib/python3.6/site-packages/reconcile-0.2.2-py3.6.egg/utils/unleash.py", line 38, in get_feature_toggle_state client.initialize_client()
  File "/usr/local/lib/python3.6/site-packages/UnleashClient-3.4.2-py3.6.egg/UnleashClient/__init__.py", line 141, in initialize_client kwargs=fl_args)
  File "/usr/local/lib/python3.6/site-packages/APScheduler-3.6.3-py3.6.egg/apscheduler/schedulers/base.py", line 443, in add_job self._real_add_job(job, jobstore, replace_existing)
  File "/usr/local/lib/python3.6/site-packages/APScheduler-3.6.3-py3.6.egg/apscheduler/schedulers/base.py", line 859, in _real_add_job replacements['next_run_time'] = job.trigger.get_next_fire_time(None, now)
  File "/usr/local/lib/python3.6/site-packages/APScheduler-3.6.3-py3.6.egg/apscheduler/triggers/interval.py", line 66, in get_next_fire_time
return self.timezone.normalize(next_fire_time)
AttributeError: 'backports.zoneinfo.ZoneInfo' object has no attribute 'normalize'

Please either pin-point the tzlocal version you depend on or, at least, pin-point the maximum major version to tzlocal ~= 2.0.

If app developers don’t pin their dependencies somehow then it’s their fault if their builds break. Assuming that they can update dependencies across major version changes without ever encountering backwards compatibility issues is simply ludicrous.
