[boost] [date_time] Ordering non-overlapping time period

Subject: [boost] [date_time] Ordering non-overlapping time period

The documentation for time_period suggests that for two periods tp1
and tp2, tp1 < tp2 if tp1.end() < tp2.begin() i.e.
!tp1.intersects(tp2).

http://www.boost.org/doc/libs/1_58_0/doc/html/date_time/posix_time.html#date_time.posix_time.time_period

But I can see that the following works:

time_period tp1(second_clock:local_time(), hours(2));
time_period tp2(second_clock:local_time() + hours(1), hours(2));

assert(tp1.intersects(tp2));
assert(tp1 < tp2);

The behavior seems legit - tp1.begin() < tp2.begin()/ The
documentation says nothing about overlapping periods.
