Ok, not horrible. Although I'd suggest not testing in a terminal window while running X. The time jumping will confuse X input timing and the screensaver, to the point that the machine may not be dead, but it isn't exactly usable. Do it in a virtual console. Again, making the limit tighter (one second?) and perhaps not trusting insane values too much at walltime clock update time either, might make it all work smoother still. I did manage to confuse systemd with all the garbage the kernel spewed, with a lot of stuff like: systemd-journald[779]: Failed to write entry (9 items, 276 bytes), ignoring: Invalid argument showing up in the logs, but I'm writing this without having had to reboot the machine.
