As far as the airlines are concerned it's up to them, but most accept it.
No need for the "BS flag", I'm just trying to be helpful. If you have something constructive to say, just say it nicely. Or maybe you're defensive about it because you're a time-buyer yourself...
Perhaps I wasn't clear enough on the original question...if the operation requires a SIC it is valid time, even if the airplane was originally certified for one pilot only. But this has to be an FAA operational certificate requirement, NOT just an insurance or company policy kind of thing.
Also, an airplane which is certified for either single or dual pilot operations could be counted as SIC if it is being operated in dual pilot mode.
