new date time inputs

The current new date time inputs cover a number of interesting and broad use-cases of various levels of granularity for absolute date and time input types:

* month          (specific year, month)
* week           (specific year, week (implied month(s)))
* date           (specific year, month, day)
* datetime       (specific year, month, day, time)
* datetime-local (specific year, month, day, time, timezone)

As well as one floating time input:

* time           (specific time, but no specific day, month or year)

This set is missing a few date time inputs that would make sense in such a more complete collection of granularity and floating (non-absolute) date time inputs:

* year      NEW: (specific year)
* month          (specific year, month)
* week           (specific year, week (implied month(s)))
* date           (specific year, month, day)
* datetime       (specific year, month, day, time)
* datetime-local (specific year, month, day, time, timezone)

and

* month-day NEW: (specific month, day)
* time           (specific time, but no specific day, month or year)

Use-cases:

• year - see the time element year only use cases
• month-day - see time element month day only use cases

The use-cases for each of these new inputs are documented in proposals for allowing the respective levels of granularity/floating date/time support in the time element.

Opinions / discussion:

• +1 Tantek - any implementer that is going to the trouble of properly implementing the existing 6 new date time inputs will find it fairly easy to implement two additional variants, and this more complete model of date and time inputs will be easier to remember for web authors (fewer exceptions to remember).
• +1 Andy Mabbett - Per the above, and examples/ use cases on time element.
• ...
