Dec 06 08:03:38 laptop systemd[823]: Time has been changed
Dec 06 08:03:38 laptop systemd[916]: Time has been changed
Dec 07 08:00:32 laptop systemd[1]: Time has been changed
Dec 07 08:00:32 laptop systemd[823]: Time has been changed
Dec 07 08:00:32 laptop systemd[916]: Time has been changed
-- Reboot --
Dec 07 08:02:46 laptop systemd[836]: Time has been changed
Dec 07 08:02:46 laptop systemd[1]: Time has been changed
Dec 07 08:02:46 laptop systemd[926]: Time has been changed
