query widget, sort results by newest first.

HI I am using the ArcGIS app. builder for Flex. I want to ask if it is possible to sort the results from the query widgets by newest first. I use the standard query widget included in the app builder with an editable feature service and a refreshing time of 1 minute. Until now the results are sorted with the oldest entry first and not the newest entry first as I would like.
Any help would be appreciated. Thank you,
