the .full extension is for names only, not dates. If you want to use custom field variables, you will either have to modify the forms and add custom fields that you can reference. For instance, all my users have a generic email address at each location, but I wanted to have the name of the person submitting the ticket referenced so when we call to resolve the issue we know who to ask for. I called the variable namesubmitter and in my template I put a table --- From : %{ticket.namesubmitter} --- so that we can quickly see who put the ticket in.
