Just created a workflow to create a report from two lists. When I copy my detail list items, the date fields created in the new list are 1 day less than they are in the detail file. Since all I do is copy them from a query into a variable and use that variable for the item creation, I'm confused and think I've got a bug.
Worked around the problem by doing a direct lookup for each field. My original solution of doing a Query and collecting the items in variables should have worked.
