Zenon logic extract timestamp of variable that is sent over over IEC101

Hi, 

In Zenon logic i am using the 870 slave in balanced mode. When i receive a times signal over IEC101 like a TID14 or TID4 i want to extract that timestamp that is sent.  

VsiGetTime just returns 0. I am online in logic and i can see the value change.  

In the picture you can see what the active sender is sending.
