PID1 getting stuck printing "systemd[1]: Time has been changed" continuously #1143
Description
By setting the date to sometime in 2038, we can make systemd getting stuck printing systemd[1]: Time has been changed over and over again.
Seems like timerfd the manager creates has always an event for us to execute. I am not sure if this is a problem specific to our 32 bit setup (kernel / libc / systemd) or a generic problem. Would be nice if someone else can test it on their 32 bit setup.
