Insertion of Leap Second
Hi All,

We are running the HP-UX 11.11 and Linux AS 3.0. so, shall we need to make any changes for leap second i.e. insert the leap second on 1st Jan 2006 or does the system have some setup which would take care of this automatically.

Please advise.

Regards,
Inder

If you are running NTP correctly, the system will handle it. Otherwise, you will be off by a second...but without ntp, you probably were already off by more than that anyway.

The NTP solution: after 11:59:59 on December 31, ntp will retard the clock to try to freeze time for one second. During 12:59:60, the clock will still read 12:59:59. But time must advance, so each clock read will advance the microseconds by one. At 00:00:00 on Jan 1, the clock is back in sync with the true seconds. So during the second 12:59:60, the clock will be wrong by nearly one second. After that second, no trace of the leap second remains.
