Hasn't this been implemented in some version of glib already?
GLib's monotonic timer is documented as "It may or may not continue to tick during times where the machine is suspended". On Linux and BSDs it uses bare clock_gettime(CLOCK_MONOTONIC), which isn't suspend aware in Linux (CLOCK_BOOTTIME is supposed to be used as drop-in replacement for such cases), but seems to be on at least OpenBSD. >> I have an implementation which in stead of using CLOCK_MONOTONIC uses >> CLOCK_BOOTTIME_ALARM.
