{{{
local_tz = pytz.timezone(""Asia/Ust-Nera")
models = Model.objects.annotate(
created_at_month=ExtractMonth('created_at', tzinfo=local_tz)
)
}}}

When evaluating the queryset it fails with:

{{{
DataError: time zone "Asia/Ust+Nera" not recognized
}}}

The "+" in "Asia/Ust+Nera" is suspicious.I have confirmed this fails with
other timezones with hyphens, such as "America/Port-au-Prince".

I have also confirmed my postgresql DB supports these timezones:

{{{
SELECT
name,
abbrev,
utc_offset,
is_dst
FROM pg_timezone_names
WHERE name !~ 'posix'
ORDER BY name asc;
}}}
{{{
```
Asia/Ust-Nera | +10 | 10:00:00 | f
...
America/Port-au-Prince | EDT | -04:00:00 | t
```
}}}
