    I tried a number of high satellites, starting with Midas 3-9 and USA 144,
    but none had a pass spanning Oct.27 03:00, which is our switch time.
    
    Centaur #25035 did culminate at 01:47:18 Local Daylight Time for (a place
    near) my Malma location, and 'End' at 03:06:06 Standard Time !
    
    But I couldn't see what the star map looked like, because it aborted with
    Microsoft VBScript runtime error '800a01a8'
    Object required: ''
    /PassDetails.asp, line 315

    The main reason is that all users can compare and analyze observations
    without repetitive and error-prone conversions, and the logic of a uniform
    time scale running from 0 to (near) 24 in a day, instead of 12 am - 1 am -
    11 am - 12 pm - 1 pm - 11 pm - 12 am.
