[PATCH v3] Avoid timezone confusion

[Daniel Axtens]

Hi Veronika,

I have become briefly sidetracked by Docker's default behaviour to set
the timezone in the container to UTC. However, I did have 1 question:

This migration is numbered 24, and depends on 23. I only see migrations
up to 21 in master. I assume you've accidentally based this on some
internal patches. I fixed this up so you don't need to respin, but I
just wanted to check that there wasn't anything in the missing
migrations that you needed for this patch.

Regards,
Daniel
