PokerTracker

I want, in the report "View Stats > T > By Date", to have a stat which displays the total of hours I have spent playing tournaments.
If I add the "Real Hours - Tournament" it does something strange, maybe this is not the stat to add.

Thanks

Adding that stat will break down the report into one line per tournament. The By Date report should show you real hours played in the Hours column which is fourth from the left by default. If you don't see it there, right click the report and click Configure Report and reset it to the defaults and you should see it displaying after that.

IN my case it displays "Hands/Hr", not total hours

Are you looking on Statistics or Results? To see Hours you'll want to be on Results -> Overview.
