It doesn't appear that the cron jobs in the inspector have been running in some time, I am guessing this happened around the time I moved from using the wp-cron call every page load to running all the cron jobs from within the user crontab via curl.
Does the SimplePress cron jobs get called with /wp-cron.php?doing_wp_cron or is there separate calls that need to be made?
Thanks,
Michael
