    Besides, the almanacs have been on UT since when - mid 70s? (and thus pretty 
    much "disconnected" from "sun time"). 
    
    I would think that as long as the almanac time coincided with time received 
    from a radio time signal (or maybe an "atomic" watch in this modern age), the 
    actual "real" time scale (however it's defined - leap seconds or none) would 
    be irrelevant (i.e. as long as we can obtain an accurate date/time for a 
    celestial event, whatever time happens to be reflected on our assorted 
    timekeepers is basically irrelevant to the navigation problem).
