We have different weekly rotation in different report suites. For eg: Sun-Sat and Friday - Thurs. As a result when we go into site metrics in site catalyst and run unique visitors(any report) for say 6 months and granularity as monthly, we see different formats in different report suites. Client care has identified the problem as week rotation different for different report suites.
I would like to raise this as a feature request where the date format is consistent across report suites.
