We log it as "I" time in SHARP and it shows up on the NAVFLIR, but there isn't a column for it in our logbooks. I usually just make a remark so that I can remember.
Anything where I have a student upgrading (fleet upgrade to level 200, 300, etc) and flights that I did in the tracom with students I log as I time. We also do "route checks" where a new AC is signing for the jet but we are riding along to supervise. I that case, I also log I time which I then count as PIC time in my civilian log.
