    O.K., I agree with you.  I was doing the calculations based on the
    orbital periods.  I was surprised I came as close as I did - I was mainly
    doing quesswork; I wasn't even sure what I was doing.
    
    Is the epoch defined when a satellite passes a certain longitudinal point
    on the globe (perhaps the Central/Greenwich Meridian) ?
