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'. Regards, Malte
