FlyChicaga is right ...
FlyChicaga is absolutely right ... kudos. Simulator time would not be included in total time whether it is a full-motion Level D or a Frasca (and I have both in my book). Do log the approaches (which count toward IFR currency) and the landings (which count toward landing currency if the sim is approved for landings ... generally Level C or D), but remember that one can not obtain flight time strapped to a hydraulic box strapped to the ground.
Certain airlines, and many insurance companies, will allow the time to be included in total time, multi time, turbine time, etc. Personally, I don't record it as such in my logbook. However, I know exactly what it is from reviewing the "simulator" entries in my logbook, and I can readily do the necessary math should any future insurer or employer care to know.
CVS also put the right point on it ... it is outstanding experience, any way you slice it. Could I fly an actual DC-9 based on my 20 hours in a Level C simulator? Maybe. Am I a better overall pilot for having had the experience, in any case? Absolutely.
Tailwinds, y'all ...
