Re: Planet Earth Slowing 0.5 Second/Day(!?!!)

I must correct my hastily posted statement below.  It is NOT 54.87
seconds/year in 1986, but had slowed BY some 54.87 seconds by 1986
versus what was being reported. My appologies.  Here's the quote from
the Troubled Times page I referenced:

    In January 1986 the difference between ET
    (ephemeris time)or TDT (terrestrial dynamic
    time) and UT (universal time) was 54.87
    seconds, UT being behind TDT; that is
    TDT-UT=Delta T=54.87 seconds.
