@Shaun Thanks but unfortunately the RSS feed plugin seems to be having some issues (at least for me), particularly with not grabbing all posts and/or duplicating them.
I'll keep my eye on the rss thread and see if it gets any updates.
How can we fetch all the posts using timestamp.
For eg.:- get all the posts which was posted yesterday.
Make a request to https://community.nodebb.org/api/recent/posts/day
This will give me the complete day posts and I'm looking for something like get all the posts from 9:00 AM to 12:00 PM.
