VU- LRT simulink model

Hello guys,

I want to model the time in simulink model. The time as an output is required. i need to analyse the data being recieved from NXT is getting lost or not. The model which i have installed on NXT is done by using VU_LRT toolbox. The model is transmitting the data which is being displayed on Matlab-sceen when i call function file xyz.m but the system time in ticks/sec/ms is not getting saved anywhere. Though it might be simple but i am unable to do that. Please help me to model the time block and save the time along with the other output datas. You can refer VU-LRT samples to get an idea. Thank you.
