Scheduler module not working even after cron run Installed 'Scheduler module' and try to publish a content on specific time. But it seems like it is not working.

I tried with  'Run cron manually' also, But it doesn't ,While trying with Scheduler light weight cron it is working.

Why is it not working?
Step: 1. First of all u have to uncheck the published node content types..

Then u have to set the schedular time for particular node 

Then U can use Rules module to publish.
