    Using what ted molczan said.
    
    Adjusting for Earth's rotation is not difficult, but it can be tedious.
    An easy method is to adjust the epoch by the desired time increment. For
    example, to compute the path of an object if it arrives 2 min early,
    subtract 2/1440 from the epoch. The above epoch would become
    02115.12912960 - 2/1440 = 02115.12774071 .
    
    I have adjusted the orbital elements for USA 102. They start with the the 
    old orbital element, and the epoch is adjusted up until that sat being 20 
    munutes early.
    
    For example the USA 102-2 means this element has it epoch adjusted for it 
    being 2 minutes early. And USA 102-4 means 4 minutes early, and so on.
