I added the date picker mode to Date rows so that it's possible to have a date picker, a time picker, a date and time picker or a countdown picker.
I'm no Cocoa expert so I hope that this code is okay regarding the UIDatePicker class.
Add picker_mode to select date, time, date and time or countdown mode…

Add spec for picker_mode
The :datetime mode would need a custom formatter, I don't know what the output should be regarding the format so I left it as a standard :date mode.
