It's not strange once you realize the second is NOT defined as 1/60 minute or as 1/86400 day, and hasn't been for a half century. Doesn't mean it doesn't cause problems, however. >So: if they adjust the length of the day, they also adjust the length of >the second. Nope. It's like leap years. We adjust the length of the year, and of February. By doing so, we aren't adjusting the length of the day just because February is supposed to have 28 days and the year is supposed to have 365 days. Leap seconds create a "minute" with 61 seconds and a day with 86,401 seconds, just like leap years create a February with an extra day and a year with 366 days. (I have watched a leap second aware clock last time there was a leap second. It displayed 23:59:58, 23:59:59, 23:59:60, 00:00:00, 00:00:01...)
