Mirror with Time span

[chota300]

I have a Mirror job in which I set the Time span to last 31 days.
Source files from the last 31 days are copied to the target directory.
As a Mirror job, I expected files older than 31 days in the target directory to then be automatically deleted.
They are not.
Either my expectations are incorrect or I have an error in my job.
Or maybe this is a small oversight in a Mirror job.
Thank you.

Your expectations are incorrect. FFS ignores data outside of its filters entirely
