Ocean Tides and the Earth's Rotation (2001) (core2.gsfc.nasa.gov)

>Currently the secular change in the rotation rate increases the length of day by some 2.3 milliseconds per day per century. [emphasis added]

>suppose the rotating earth is our clock and it's been 100 years [...] Then after 1000 days our earth clock loses about 2.3 seconds,

I think the math here is very wrong, or else I haven't had enough coffee yet.

>it's been about 100 years so now each day is 2.3 milliseconds longer

>after 1000 days 1000 * 2.3 milliseconds = 2.3 seconds

I don't think the example helps at all to explain the concept, but I think the math is right
