Returns a text field that allows the user to input a date and time.
 Automatically validates itself and recovers to a template if blanked out.
 This field uses moment.js to parse the date and set the values on a
 set of hidden Rails `datetime_select` fields.
 Options are forwarded to the hidden `datetime_select` group.
