Lots of questions about how to pull your time back out once you go ahead and add all your time tracking data into RTC. Working on tracking down more details but at first glance it looks like this is fairly straight forward. Unfortunately at GA this was not included in the ETLs for CLM DW so you need to use BIRT.
Try the LIVE_SNAPSHOT create a data set using the Jazz Simple Data Set and select the table com.ibm.team.workitems.TimeSheetEntry. Not the most comprehensive bit of advice but if you take a look at that columns of the table you will see that this gives all you need to query by project, code, user, and date so should be good for reporting on where you time is being spent if you are using time tracking today.
