Description of problem:
SELinux is preventing /usr/lib/systemd/systemd-timesyncd from 'write' accesses on the directory /run/systemd/timesync/synchronized.

*****  Plugin catchall (100. confidence) suggests   **************************

If you believe that systemd-timesyncd should be allowed write access on the synchronized directory by default.
Then you should report this as a bug.
You can generate a local policy module to allow this access.
Do
allow this access for now by executing:
# ausearch -c 'systemd-timesyn' --raw | audit2allow -M my-systemdtimesyn
# semodule -X 300 -i my-systemdtimesyn.pp
