Comment 8 for bug 1002639

I make report as following:

web client side
1) Add code to webclient, that it send through context timezone shift from UTC (from browser view).

server side
1) Get timezone shift from context
2) Read table
3) Correct datetime with timezone shift and save it to new temporary column (datetime in local timezone for a particular user)
4) Group and filter on corrected datatime (in this point code the same, that without timezone)
