I've updated that section to give a few more details. > I had the impression, falsely, from the way people were talking that it was > an OS thing, and not an NTP thing. It's handled by both ntpd and the OS in the common situation of a kernel with precision timekeeping extensions. ntpd notifies the kernel loop discipline which takes care of implementing the insertion. > Still don't know if Windows supports it. Windows doesn't have those extensions. When the kernel loop discipline is unavailable or disabled, the daemon loop discipline implements insertion by stepping the clock backward one second on POSIX systems. On Windows, the clock is run at half speed for two seconds. > I also see that entry format is > different for the current entry compared to all previous, so I hope the > white-space count isn't important.... I'm not sure what you're referring to. Here's the prior entry and the latest: 3439756800 34 # 1 Jan 2009 3550089600 35 # 1 Jul 2012 You can verify the leapsecond file is loaded by seeing tai=34 among the output of ntpq -crv Cheers, Dave Hart _______________________________________________ questions mailing list [email protected] http://lists.ntp.org/listinfo/questions
