Question date format - lapsed time

i have a problem with the time on the latest module.

on my old site (j1.5) i hade a "lapsed time" format in the module (accepted standard settings from the forum)
awesomescreenshot.com/0dciuf7fc

at the new site (j1.7) with the last GIT source from the kunena-latest module i only have always this time format.
imm.io/8cjt
how can i get a lapsed time in the module?
The module does not take the time-format witch i have chosen from the Forum ...

default config in kunena:

Message Time Format - 22 hours, 13 minutes ago (Lapsed Time)
Hover Message Time Format - 17 Aug 2011 14:32 (Date Time)

my Kunena config

Hello,

I need to look this more closer

i send you the WEBSITE Link @ PM
on the site you find the module on the right site, could you take a look please

Do you have tried to change the date format in module configuration settings ?

yes have tried some time configurations, but finally i would like to have the same lapsed time setting as the forum has
