what are the directories systemd-private-xxxxxx ?

I see a lot of empty directories in /tmp and /var/tmp that have names like systemd-private-xxxxxx. Does anyone know what are the purpose of these directories? They seem to accumulate in /var/tmp.

I have no such directories.  What services are running when this happens?

They are created by services with PrivateTmp=true (usually ntpd). They should be cleaned automatically after haven't been used for the amount of time specified in /usr/lib/tmpfiles.d/tmp.conf (30 days by default)
