title: Run custom cron on wordpress
body: <p>Just working on a custom wordpress plugin. It will have an export and import function that need to be run at very exact times. So for those 2 functions I am ditching the wp-cron and set up cron jobs via crontab.</p>
  
  <p>But how do I run only those 2 functions in this plugin but nothing else?</p>
  
  <p>Thanks for your help.</p>
