Fix date picker wrong on certain timezones (#5972)

Timezone with a negative offset weren't working good with date pickers.

I split the logic for display and parsing between date only and
datetime.

Date time is sending and displaying using timezone, and date only is
sending and displaying by forcing the date to take its UTC day and month
and 00:00:00 time.

This way its consistent across all timezones.
