    Well, my Long Term Almanac is nominally good up to the year 2050 and will
    actually work OK up until 2060. So this is a very real question for me.
    I am assuming that if leap seconds are abolished, anyone using my tables -
    which assume GMT, or UT1 as it is called these days - will know the
    difference between broadcast time and GMT and use this as a correction to
    broadcast time.
