How do we call cron or lightweight cron on exactly scheduled node times?

Hi Mudassar,
Scheduler publishes the nodes during cron, as you know. So if you want a node published very precisely at a time which is inbetween existing cron runs you simply need to have cron runs more frequently. There might be an overhead on some sites if the full cron job is run frequently, so this is why we have provided the lightweight cron job scheduler/cron/{access key}. You can set up a crontab to call this url every five minutes, or even every single minute if you really want. It will only do Scheduler processing so is very quick and will not overload your server.

Do you have access to your hosting crontab set-up? Or are you setting up the jobs manualy in a terminal window?
To run the Scheduler cron every 5 minutes the command might look like:

*/5  *  *  *  *  curl http://your-path-to-drupal-root/scheduler/cron/{optional access key} > /dev/null 2>&1

That's good to hear. Let me know if you want any more help with crontab.

I have added that link on setting up cron jobs to the project front page.
Closing this issue now.

Thank you @jonathan1055. Your comment #2 works for me too!
