date(1) doesn't handle leap-seconds?



According to the leapseconds file, there was a leap-second added at the end of 2005, and the second following 2005-12-31-23:59:59 was known as 2005-12-31-23:59:60.

However, it seems that our date(1) utility doesn't know about this. If you ask it for the time difference between 2006-01-01 and 2005-12-31, it still calculates the number of seconds as 24 * 60 * 60 and doesn't have an extra second!

$ TZ=GMT; export TZ
$ echo $(( $(date -ju '+%s' 200601010100) - $(date -ju '+%s' 200512310100) ))
86400
$

Is this a bug?
