We need a monotonically increasing time source independent from the
system time. The hotplug events are tagged with a timestamp to
determine its age for timeout handling. If we use time() or similar and
the init scripts are running ntpdate or changing the timezone from a
localtime BIOS clock, set by some other stupid OS, udev gets confused.
So I use the uptime seconds now, any better idea?
