* Sometimes a merge is performed on a machine with faulty time.
* This makes the traversal of the graph, when trying to find out if B
* is merged into T, complex since the algorithm uses the time stamps
* of commits to find the best route.
* When for example O(ld) has a very old time stamp compared to one of the
* commits (N(ew)) on the upper route between T and F(alse base), the route
* to False is deemed the better option even though the alternate route leeds
* to B(ase) which was the commit we were after.
