Blogposts created same day are not sorted correctly

Note - This bug doesn't affect version 6.x. It is affecting version 7.x

Summary

When several blogs are created on the same day, they are not getting sorted based on created DateTime. The last blog created appears at the end of the blog list.

How to replicate

1. Create a blog post called "Blog 1".
2. Add some content. Close the editor and save it.
3. Create another blog post and publish it as "Blog 2".
4. Add some content to Blog 2. Close the editor and save it.
5. Create another blog post and publish it as "Blog 3".
6. Add some content to Blog 3. Close the editor and save it.

Expected results

On the Blog post page, the order of the blogs should be like below

• Blog 3
• Blog 2
• Blog 1

Actual results

The blogposts are instead listed in this order (top to bottom):

• Blog 1
• Blog 2
• Blog 3

Note

The blog created on the next day will appear at the top of the blog page list. For e.g., if Blog 4 is created on the next days, the order of the blogs in the blog list is

• Blog 4
• Blog 1
• Blog 2
• Blog 3
