问题
Use Case: User can post anytime on Facebook even after 6 months. In the backend, I'll be storing the posts with user content and will be running a cron job to make post through access token. This way I can post on user/page/group withoout any issues. But it seems cron part is not very clear to me. Consider following scenario:
User A wants to schedule his post at 7 pm on Thursday. User B wants to schedule his post at 7:05 pm on Thursday. User C wants to schedule his post at 7:03 pm on Thursday. User D wants to schedule his post at 8 pm on Thursday. User E wants to schedule his post at 7:10 pm on Thursday. and many more.....
Now, How can I put a cron job to meet all these requirements? My point is we can run cron job after every 5 mins or something like that..may be on hourly basis but this way I may skip some posts. How can I make sure I don't miss any of the post. Also, I can run a job in background continuously but that will put extra load on the server.
I found following thread but still not able to correlate my problem to this. Also, I got this solution as a part of my previous question which can be found here.
Any suggestions are welcome.

You can run a Cron Job every minute. If you just check for posts to schedule, it will not really be a big problem for the server.
