Making sure WordPress Cron runs

[szepeviktor]

I've found no way in core to look up when WordPress Cron ran the last time.

<?php

add_filter(
    'pre_set_transient_doing_cron',
    static function ($value) {
        update_option('cron_last_run', $value, 'no');
        return $value;
    },
    0,
    1
);

This MU plugin records the time of last run in an option called cron_last_run.

Then it can be compared to current time: wp option get cron_last_run

(I use Linux cron jobs to run WordPress Cron)
