    i've run across another anomaly... it may not be a big thing (only two seconds 
    back in time) but i discovered it because my TLE software expects that TLEs will 
    advance in time when it updates an object's entry... the situation is that the 
    newest entry is older than the previous one (by two seconds) so the previous 
    entry is retained...
    
    i'm just not sure how it should be handled...
    
       a typo made before is being corrected now?
       a typo made now is needing to be corrected?
       no typo, previous is correct?
       no typo, current is correct?
       no typo, both are correct?
