What proposals are there for eliminating leap seconds? I don't see how you can get around them without either redefining the second, or putting off a bigger adjustment later.

The problem is that leap seconds might have made sense when time keeping was accurate at the millisecond level but now that time can be measured at the nanoseconds level (at the speed of Computing, essentially) such changes are to big and cause problems, especially if they are negative. Instead, applying by smearing the time over a period (see Google’s approach) is a less dangerous way of handling the situation, but now you’ve got computers that might not agree on time exactly.

As a result it is easier to abolish leap seconds and just live with the fact that in 30,000 years time that noon might not be directly overhead.
