Relationships      
Parents 时间单位 The class of temporal durations (instances of TimeDuration) and positions of TimePoints and TimeIntervals along the universal timeline (instances of TimePosition).
Children 时距An interval of time. Note that a TimeInterval has both an extent and a location on the universal timeline. Note too that a TimeInterval has no gaps, i.e. this class contains only convex time intervals.
 时点An extensionless point on the universal timeline. The TimePoints at which Processes occur can be known with various degrees of precision and approximation, but conceptually TimePoints are point-like and not interval-like. That is, it doesn't make sense to talk about how long a TimePoint lasts.
