Description of problem:
The issue probably arised after changing Time/Date source on newly installed Fedora 22. There are 20 more similar SELinux notifications from different apps with the same issue with /etc/localtime.
SELinux is preventing NetworkManager from 'read' accesses on the lnk_file /etc/localtime.

*****  Plugin catchall_labels (83.8 confidence) suggests   *******************

If you want to allow NetworkManager to have read access on the localtime lnk_file
Then необходимо изменить метку на /etc/localtime
Do
# semanage fcontext -a -t FILE_TYPE '/etc/localtime'
где FILE_TYPE может принимать значения: NetworkManager_etc_rw_t, NetworkManager_etc_t, admin_home_t, alsa_home_t, antivirus_home_t, audio_home_t, auth_home_t, bin_t, boot_t, cache_home_t, cert_t, cgroup_t, chrome_sandbox_home_t, config_home_t, cvs_home_t, data_home_t, dbus_home_t, debugfs_t, device_t, devlog_t, dhcp_etc_t, docker_home_t, etc_runtime_t, etc_t, fetchmail_home_t, file_context_t, fonts_cache_t, fonts_t, gconf_home_t, git_user_content_t, gkeyringd_gnome_home_t, gnome_home_t, gpg_secret_t, gstreamer_home_t, home_bin_t, home_cert_t, home_root_t, httpd_user_content_t, httpd_user_htaccess_t, httpd_user_ra_content_t, httpd_user_rw_content_t, httpd_user_script_exec_t, icc_data_home_t, iceauth_home_t, irc_home_t, irc_tmp_t, irssi_home_t, kismet_home_t, krb5_home_t, ld_so_t, lib_t, local_login_home_t, locale_t, mail_home_rw_t, mail_home_t, man_cache_t, man_t, mandb_home_t, mozilla_home_t, mpd_home_t, mpd_user_data_t, mplayer_home_t, mysqld_home_t, named_cache_t, net_conf_t, openshift_var_lib_t, openvpn_etc_t, polipo_cache_home_t, polipo_config_home_t, postfix_postdrop_t, proc_t, procmail_home_t, pulseaudio_home_t, rlogind_home_t, root_t, rpm_script_tmp_t, rpm_var_cache_t, rpm_var_lib_t, rssh_ro_t, rssh_rw_t, sandbox_file_t, screen_home_t, security_t, selinux_config_t, shell_exec_t, spamc_home_t, speech-dispatcher_home_t, src_t, ssh_home_t, sssd_var_lib_t, svirt_home_t, sysfs_t, system_conf_t, system_db_t, systemd_home_t, telepathy_cache_home_t, telepathy_data_home_t, telepathy_gabble_cache_home_t, telepathy_logger_cache_home_t, telepathy_logger_data_home_t, telepathy_mission_control_cache_home_t, telepathy_mission_control_data_home_t, telepathy_mission_control_home_t, telepathy_sunshine_home_t, texlive_home_t, textrel_shlib_t, thumb_home_t, tmp_t, tvtime_home_t, udev_var_run_t, uml_ro_t, uml_rw_t, user_fonts_cache_t, user_fonts_config_t, user_fonts_t, user_home_dir_t, user_home_t, user_tmp_t, usr_t, var_run_t, var_t, virt_content_t, virt_home_t, vmware_conf_t, vmware_file_t, wine_home_t, wireshark_home_t, xauth_home_t, xdm_home_t.
Затем выполните: 
restorecon -v '/etc/localtime'

If вы считаете, что NetworkManager следует разрешить доступ read к localtime lnk_file по умолчанию.
Then рекомендуется создать отчет об ошибке.
Чтобы разрешить доступ, можно создать локальный модуль политики.
Do
чтобы разрешить доступ, выполните:
# grep NetworkManager /var/log/audit/audit.log | audit2allow -M mypol
# semodule -i mypol.pp
