This is speeding up. Per data gathered directly from the Navy Earth
Rotation Service shows the increase. If in 1972 the differed was 32
seconds, then the 64.0908 seconds reported by NOW does not seem
excessive. BUT, the RATE is increasing!
In January 1986 the difference ... was 54.87 seconds.
In January 1, 2001 the slowing was 64.0908 seconds.
The International Earth Rotation Service also updates
these data weekly. Thus I was able to incorporate in
this plot the slowing data including June 1 of 2001.
... The very recent data from the International Earth
Rotation Service show numbers which allow
calculating Delta T for June 13, June 14, and June 20
of 2001:
June 13, 2001, Delta T = 64.208477 seconds
June 14, 2001, Delta T = 64.208550 seconds
June 20, 2001, Delta T = 64.209395 seconds
So, the CHANGE of Earth slowing during one day was
0.000073 second or 73 microseconds at that time; the
change during one week was 0.000918 second or
918 microseconds. This very small daily change is
very hard to measure with common time devices.
