My settings uses Australia/Melbourne and Postgres stores time correctly
as UTC+10 (or UTC+11 in daylight saving time).

But as it happens I'm in New Zealand for a couple of days. So I'll
change my laptop location to Wellington tonight and log in and create
some test entries and knowing when I do that I should be able to check
the results after switching the laptop back to Melbourne time.

Now I think of it I could pretend I'm in Shanghai :)

You can see from the above that I half-believe pytz uses the system
locale to figure out the UTC offset. But I suppose it might be TIME_ZONE
in settings.

Have to go out now. I'll report back later
