How can i list the files in a directory by using time stamp filter.

pub.file:listFiles

can we specify time stamp filter in this built-in service?

No you can't. filter is only used to filter the files as per extensions (*.CSV) anystring(filename) followed by extension csv will be listed and if your file names start with timestamps example:
23-02-1998 (dd-mm-yyyy) then you can have it as (*-02-*.*) for listing all Feb files with all extensions.

or (23-*-*.txt) for listing all 23rd dated files with .txt extension.

Let me know if this clarifies you.
