Tag panel adding track time

Hi There,

i us the tag panel for input and i have search for a way to add the track time within the panel but didn't come across of any way to add this. can this be done and if so where can i find out how to do this please. i'm looking for hh:mm not the length.



What is the differnce between track time and length?
If this is an attribute that is addressed with a property field with a name that starts with an underscore, then it cannot be used for the tag panel.
