Editing a draft does not set `post_date_gmt`, but quick editing a draft does

(It's all in the title…)

As a bonus, too, you cannot clear the date of the draft to make it so that it gets published immediately: you need to manually set the date to whenever.

Trashing a draft sets its post_date_gmt field as well:

1. Create a draft.
2. Trash it.
3. Restore it.
4. The date no longer offers to publish immediately

[Denis-de-Bernardy]

A fix to all of these (bar clearing the date, but it works around the problem) is to change the following in wp_insert_post():

	if ( empty($post_date_gmt) || '0000-00-00 00:00:00' == $post_date_gmt ) {
		if ( !in_array( $post_status, array( 'draft', 'pending', 'auto-draft' ) ) )
			$post_date_gmt = get_gmt_from_date($post_date);
		else
			$post_date_gmt = '0000-00-00 00:00:00';
	}

To:

	if ( empty($post_date_gmt) || '0000-00-00 00:00:00' == $post_date_gmt ) {
		if ( !in_array( $post_status, array( 'draft', 'pending', 'auto-draft' ) ) )
			$post_date_gmt = get_gmt_from_date($post_date);
		else
			$post_date_gmt = '0000-00-00 00:00:00';
	}
	elseif ( in_array( $post_status, array( 'draft', 'pending', 'auto-draft' ) ) ) {
		$post_date_gmt = '0000-00-00 00:00:00';
	}
