So, this was really a meaningless discussion from the start. :-)
You don't *want* your clock to be in sync with civil time.

The only 'strings' with meaningful representations of TAI instants
would be what Dan is using on <URL:http://cr.yp.to/proto/utctai.html>:

  "For example, here's how UTC and TAI handled the end of June 1997:

   1997-06-30 23:59:59 UTC = 1997-07-01 00:00:29 TAI
   1997-06-30 23:59:60 UTC = 1997-07-01 00:00:30 TAI
   1997-07-01 00:00:00 UTC = 1997-07-01 00:00:31 TAI"

All other strings---that is, all other representations of the atomic
time---depends on UTC and hence depends on leapseconds (or really on
how fast earth is rotating).

I should add 'as far as I know'.
