Okay, so internally systemd is using CLOCK_MONOTONIC for the event source that counts up to RuntimeMaxSec, and CLOCK_MONOTONIC does not count the time when the system is suspended. Your use case wants CLOCK_BOOTTIME, which does count time when the system is suspended. I will work on a fix for this.

But on a GNOME login session (using X), this apparently doesn't work: the session is still running 17 hours after it should have been terminated. My guess is that systemd is ending the session by sending a signal that is being ignored by the GNOME login session? RuntimeMaxSec is not very useful if it's advisory...
