Itzï is creating the maps and a STRDS where maps are registered.
But the maps could be registered in various STRDS.

If I do the calculation, the simulation will actually ends on
2013-12-10 00:00:00 :

from datetime import datetime, timedelta
start_time=datetime(year=2013, month=11, day=15)
duration=timedelta(hours=600)
end_time = start_time + duration
print(end_time)
2013-12-10 00:00:00

So the last record is missing.
I just checked the source code and there is actually a bug that
prevents the record of the very last maps.
It should be fixed for the next release of Itzï.
