    Thank you, Derek. I have checked it out, and it still appears to be 1.96 s late.
    Greg also checked it, and found it at least 2 s late.

    Agreed, but since the orbit is very stable, and the elements are nearly
    contemporaneous with your observation, I expect time agreement to within a small
    fraction of 1 s, so something appears to be amiss. To help resolve the matter, I
    recommend that a few additional observations be made by yourself and other
    positional observers. If all observers find it ~2 s late, then the elements are
    at fault; if only your obs are late, then your timing is at fault. In either
    case, we will learn something new.
