CURRENT_DATE and CURRENT_TIME should appear without brackets

[roman4e]

In Postgresql functions CURRENT_DATE and CURRENT_TIME are keywords and appear always without brackets.

So there

pypika/pypika/functions.py

Line 278 in 53a77eb

class CurDate(Function):

Should be added

    def get_function_sql(self, **kwargs):                                                                               
        return "CURRENT_TIME" 

AND
there

pypika/pypika/functions.py

Line 283 in 53a77eb

class CurTime(Function):

should be added

    def get_function_sql(self, **kwargs):                                                                               
        return "CURRENT_TIME"

I had the same problem. Looks like there's an error in the docs. Here's what worked for me:

from pypika.terms import Term
class CurrentDate(Term):
    def get_sql(self, **kwargs):
        return "CURRENT_DATE"

This works too:

from pypika.terms import PseudoColumn
CurrentDate = PseudoColumn('CURRENT_DATE')

but
CurrentDate = Term('CURRENT_DATE')
didn't work.
