Problem whith wdates fields when using parallel load

Hi, I have a job of comparing two tables from two Informix sources and then updating the modified datas on the destination source (Informix), the problem is when I run the job, I run a dataflow for comparaison which found some differences between the two tables.
for 4 million datas, I got a little differences of 17 or 3 rows at random which are different on the fields of type date.

For example :
source: 28/11/2016 and destination 27/11/2016

When I deactivate the parrallel loading ion the destinationn table, it works fine and no divergence are noted, so is this a bug on Sap Dataservice 4 ??

plz help
