Date/time functionality seems to be missing

Here is a patch which adds date and numeric field type

You can simply rewrite your results by using twig functions to convert dates.

e.g.
to convert timestamp to date format - {{ value|date('d - m - Y') }}
to convert date format to timestamp - {{ value|date('U') }}
to convert date format to another date format - {{ value|date('U')|date('d - m - Y') }}

Thank you @AstonVictor

Its work for displaying, but not working for filter/exposed filter in date format.
