I have some files that using different date types:
some only have year "2020", others have month "2020-12", and still, some have date:"2020-12-21"
So I want to use interval. Like this:
(define-table test-date ()
((date :col-type :interval
:initarg :date
:accessor date)))
(create-dao 'test-date
:date "2020 years")
(date (find-dao 'test-date))=>((:MONTHS 24240) (:DAYS 0) (:SECONDS 0) (:USECONDS 0))
Q1. Is this is how interval
supposed to use?
Q2. How to get year?
