From Apache OpenOffice Wiki
TrueTime is a tool for profiling the performance of a Windows application.
I have used it a lot in the past, but nowadays I switched to other tools, so I don't know how well TrueTime works with current versions of OpenOffice.org.
For this reason, I don't move the information to the wiki (for now), but simply link to my old HTML version of the TrueTime HowTo.
If someone is successfully using TrueTime with OOo 3.0 or later, please let me know, and I will move the content to the wiki and redirect the HTML page to this place.
