That is, these functions can now be called on timestamp and date or time (but not on intervals):
year, month, day, day_of_month, day_of_week / dow, day_of_year / doy, hour, minute, second, millisecond.
The implementation is by calling new convenience methods for applying unary kernels to columnar values. For uniformity, this also switches a few previously-introduced implementations to these methods (year, month, day).
