According to Official WordPress Plugin Development Document: WP-Cron does not run continuously, which can be an issue if there are critical tasks that must run on time.

It’s a sign that you have ALTERNATE_WP_CRON defined in your wp-config.php In order to do some background processing (like publishing scheduled posts), WordPress redirects you to the URL with ?doing_wp_cron appended.
I know I’m three months late, but the function you want here is WordPress’ get_date_from_gmt(). The function accepts a GMT/UTC date in Y-m-d H:i:s format as the first parameter, and your desired date format as the second parameter.

I think the best way is to use WP-CLI but you’d need to write a bash script to do this. Here is one that should do it for you: WP_PATH=”/path/to/wp” for SITE_URL in = $(wp site list –fields=domain,path,archived,deleted –format=csv –path=”$WP_PATH” | grep “,0,0$” | awk -F ‘,’ ‘{print $1 $2}’) do for EVENT_HOOK in $(wp … Read more

Why don’t you just create a cron job, make a database dump and look where the info about the cron job is kept? That’s what I did.
