That seem unrelated to the now() function.  Casting a literal to a
date/time/timestamp supports parsing out certain keywords, like
'now', 'today', 'yesterday', and 'tomorrow'.  It's probably ignoring
those parentheses.

Yeah, I don't know how much the community lists can help with that
implementation.  It seems there is a bug in that version, but it
might not be present in the community version.
