It has no relevance.
It is not flying time by definition, so you cannot log it as such. It is training in a synthetic training device. The use of that device may be approved in defined quantity towards the issue of a licence or rating, but it is not logged as "flying time" in any event.
Usually there is a section at the back of a log book where the time spent in such devices can be recorded. Usually these devices are used for training purposes, but since there is no requirement (that I have ever been aware of) to designate a commander for the purpose of operating a simulator, so there is no requirement to log it.
As has already been said, you can annotate the excercise in whatever way you wish to, or seems most relevant, but it shouldn't be confused with the requirement to log flying time.
