I have a custom post type called books. The books publication date is from between 1700 and 1900.
I want to set the post date to these dates(so i can query the results sorted by year) but i can't seem to have a date set before 1970 january 1.
Is it possible to somehow do that?
post_datein the database sets correctly to any date I tried. However,
post_date_gmtis set incorrectly as Jan. 1, 1970-- the beginning of the world. So don't try to coopt that field. Do what toscho suggests.
