The time in the kernel is seconds since the epoch. To insert a second means that we'll have to delay the next second for another second. The other solution seems to be a clib -> kernel interface that knows that a leap second is active now. Then the clib could possibly convert the seconds to xx:yy:60. (I hope I did not overlook something obvious).

IMHO it's hardly worth the trouble.
