This changeset converts the display of dates and times to be just UTC to match the recent changes in the backend. This unwinds a bit of work that was done previously and allows us to start with a clean slate in how we want to approach displaying dates and times going forward. It also adds a bit of explanatory text to help users.

This makes it clearer we have tests for the code in forms.py, which
I missed initially. In future we could also split up forms.py in a
similar way, as it's currently _very long_.
As part of grouping tests for code in forms.py, I've extracted some
from test_validators.py, so that what remains is focussed on testing
the code in validators.py.
