This is not a valid time zone in pytz. In the process of reporting an error thrown by a bug in my code, Django tried to normalize the time zone provided in the project settings by passing it through pytz. pytz then complains that the time zone is unknown. Somewhat amusingly, this error is also caught by Django and goes through the same code path, quickly hitting the recursion limit. See below for a significant part of the stack trace. My temporary solution was to change `return pytz.timezone(settings.TIME_ZONE)` to `return pytz.timezone(settings.TIME_ZONE if settings.TIME_ZONE in pytz.all_timezones else 'UTC')` --- {{{
