Sounds a reasonable idea.
Under Features > Posts you can show only future posts
Each post can have a future date and time, so only those will show until that date and time
You can even add fields to a whole item type to add another value
and you can order by that value.
You can also make a separate collection for 'Posts to Die'
Otherwise it looks like you are asking for multiple time slots for an item so it can be switched on and off as you want. So how many times would suit you?
I suppose a table with multiple dual data could hold the info and a script could purge past dates.
