union

public static TimeRange union(TimeRange lhs,
                              TimeRange rhs)

Returns the union of two time ranges, that is, the range that can contain both time ranges.

intersect

public static TimeRange intersect(TimeRange lhs,
                                  TimeRange rhs)

Returns the intersection of two time ranges, that is, the widest possible range that is contained by both time ranges. Undefined behavior if the two timespecs do not overlap.
