What effect does this have on existing information in the database?
Does this mean they'll all remain UTC+12 or are they stored in UTC
format already? The Django docs [1] would lead me to suggest the
former, given that we don't have USE_TZ set to True.

I guess you can test that by setting up a deployment, creating
information, then switching this option over. I'd do this myself but
I'm not going to have time this week :(
