wp_resolve_post_date( string $post_date = '', string $post_date_gmt = '' )
Uses wp_checkdate to return a valid Gregorian-calendar value for post_date.
Description
If post_date is not provided, this first checks post_date_gmt if provided, then falls back to use the current time.
For back-compat purposes in wp_insert_post, an empty post_date and an invalid post_date_gmt will continue to return ‘1970-01-01 00:00:00’ rather than false.
Parameters
- $post_date
-
(Optional) The date in mysql format.
Default value: ''
- $post_date_gmt
-
(Optional) The GMT date in mysql format.
Default value: ''
Return
(string|false) A valid Gregorian-calendar date string, or false on failure.
