Ok, not really. It leaves them "unsorted", and it then depends on the
sort routine what happens. For me, the sort routine is stable, so they
stay in whatever position they used to be. For you, that's apparently
not the case.

However, you still leave one case unsorted: the case of both trips
being zero. Why?

Don't you want to compare when_a/when_b when trips are NULL? Turning
that "return 0" into just "return when_a - when_b;" should do that..
