Scheduler isn't starting correctly in docker

[mpstewart]

When running docker-compose up, the scheduler never seems to start correctly. The following appears in the log:

webserver_1  | 2021-03-23 17:14:17,665 INFO spawned: 'scheduler' with pid 367

The only time-related config change I've made was to set PAPERLESS_TIME_ZONE in docker-compose.env:

PAPERLESS_TIME_ZONE=America/New_York

I'm also having an issue where my document scans are being queued, but not actually being processed; I was investigating that when I found this, and I'm wondering if this is the root cause of the document processing issue.

I was able to resolve this by reverting the time zone setting I changed.
