Examples of org.linkedin.util.clock.Timespan

org.linkedin.util.clock.Timespan
This class represents a notion of timespan. Note that the time units goes from milliseconds to year. It does not go below milliseconds because we rarely use this kind of precision especially since the java vm does not support it very well. Note that above hour, the timespan is approximate. This object is immutable and thread safe. @author ypujante@linkedin.com
