[Olsr-users] Recommendation for maintaining accurate local times on nodes?

Stable OLSRd use the realtime clock, but sanatize the output. Every
times the clock moves forward for more than 60 seconds or backwards,
OLSRd assumes a millisecond passed and goes on.

the next version of OLSRd I am working on will use the monotonic clock
if available.

Steven Hawkings about cosmic inflation: "An increase of billions of
billions of percent in a tiny fraction of a second. Of course, that
was before the present government."
