A key point about default wordpress cron is that it only runs if there is traffic on the website. So if you are testing at low traffic hours you may not see a cron job run when you think it should. If you want more immediate and reliable scheduled action please google 'wordpress cron' - there is a lot of content out there about wordpress cron and alternate ways to run it. For most sites wordpress default cron is adequate.
Help - Job with scheduled time in the past????
See the point above. Click on 'Trigger cron now', then go back to dashboard and refresh the dashboard.
Run now = Reschedule to time just past
To run a job 'now', leave the date and time proposed as is (they will be in the past by the time you have looked at the screen. Then click reschedule. That will reschedule that job for that time and the job should run. You may have to click 'trigger cron now'.
The trigger cron now page is useful when you are debugging cron jobs. You may temporarily issue output and it will be visible if the cron runs on that 'trigger cron' page load.
Job rescheduled for now/soon shows in future
It probably rescheduled and ran, and then setup the next run as per it's frequency.
Refresh the cron dashboard
If you have triggered the cron and think a job should have run, then refresh the cron dashboard to see. It will either
still be there with a time in the future
moved to a much more future timeslot (recurring jobs)
disappeared - it was a one off job and it ran
No action?
If a job has no action it will do nothing. It is just there, an entry that keeps getting rescheduled. Maybe the plugin that created it got deleted? Someplugins don't know to clean up after themselves. Maybe it is just temporarily inactive? Maybe it's a bug in the creating plugin? If you don't think you need it, delete it.
Undeleting
The only way to do this is either maybe wordpress or the creating plugin will automaticaly bring the job back to life, or you ay have to reactivate the creating plugin. Yes that means deactivate then activate again.
Deleting a job - zombies that won't die
Some plugins check whether their jobs are running and if not, they recreate them.
