At no point did I use the term 'IFR'.
You make the classic mistake of confusing IMC and IFR. IFR is nothing more than a set of rules to ensure that the aircraft and crew have a minimum of equipment and skills to deal with the requirements of the airspace. It does NOT mean you are flying by sole reference to instruments, which is the whole point of the IF and Instrument Approach columns in a logbook - to prove skill in the art of instrument flying for continued retention of an instrument rating, or for the award of the same.
"Having said that, I have no idea if IF time is time in IFR or IMC....." Well, you holed yourself below the waterline there with that comment, didn't you? Hopefully you have gained from this little discussion.
