Member Data Documentation

float dtn::utils::Clock::quality = 0 [static]

Defines an estimation about the precision of the local time. If the clock is definitely wrong the value is zero and one when we have a perfect time sync. Everything between one and zero gives an abstract knowledge about the quality of time.
