Incorrect request date and time are printed in the report.
This problem occurs when your proxy server maintains its date and time in GMT - without adjusting them for your local time zone. You should manually adjust the time by setting the "Time zone offset" parameter in the settings. Open the "Settings | Data Sources", select appropriate list item, open "Import Settings" dialog and on "Optional" tab select a valid time zone from dropdown list.
When you are done adjusting these settings, clean up the database completely (remove all database files) and redo log files importing.
