Time (`TimeField`) and Date time (`DateTimeField`) fields not supported

[kbayliss]

Using either TimeField or DateTimeField results in an unstyled/default field (i.e. one that does not look like the GOV.UK Design System).

This is because the GOV.UK Design System does not contain a pattern for time fields or datetime fields.

While there's no official pattern for these fields, alphagov/govuk-design-system-backlog#173 contains some suggestions on how to work around this until official support is (hopefully) added, which could be implemented within tbxforms as an interim solution.

Just noting for future ref that we have been on the quest for an accessible date-time picker for Wagtail for years. The only option we found to have no accessibility issues is the React Spectrum’s DatePicker. Supports date and time. Is more accessible than browsers’ default fields. Supports internationalization, seconds, time zones, and a bunch of other useful features.

For most use cases I wouldn’t recommend it, a plain-text field with validation for multiple formats is much more accessible (for time in particular). But as far as date and time pickers go it’s the only one that’s met our (accessibility) testing criteria. Some other pickers are ok for dates only.
