Public bug reported:

in http://bugs.ntp.org/show_bug.cgi?id=2745
 | With older versions it was possible to use the -x option to avoid upsetting
 | applications running on the system when the clock is stepped due to a leap
 | second.
 | 
 | It seems in 4.2.6 was added support for inserting/deleting leap seconds on
 | systems without kernel discipline. However, the clock is now stepped even when
 | the -x option or tinker step is used to disable stepping.

I'm not sure this bug could affect Ubuntu's ntp packages, but I believe
that this information is IMPORTANT for some ubuntu users.
