The data displayed in the User Type Chart output from the Enterprise Dashboard does not match the timings for the actual sessions it depicts, and are a day out of synchronisation.
In the example attached, the data shows the following for CAI Power Users:-
1 user logged in on the 24th June
0 users logged in on the 25th June
2 users logged in on the 26th June
The 2 users we logged in on the 27th of June - no users being logged in on the 26th
Did an SQL query against the Enterprise Dashboard database, which confirms the users logged in on the 27th - it also shows that the user graphed for the 24th was actually logged in on the 25th
The system is therefore displaying date one day earlier than the correct time
