0003 """ This script can be used to run manually the dcs o2o over an interval of time,
0004 dividing it in smaller intervals. Running on an interval too big can cause
0005 a result of the query to the database so big that the machine runs out of memory.
0006 By splitting it in smaller intervals of a given DeltaT it is possible to keep
0007 under control the memory used.
