Not sure if Obsidian has something built-in for this. But if you install the dataview plugin you can create your own views with this kind of info.
For example the following code would be used to create a table with the 30 most recently created files, sorted by creation timestamp:
TABLE file.ctime
SORT file.ctime DESC
LIMIT 30
(I recommend putting a limit on it, else it will try to show all of your notes)
