[ntp:questions] WARNING: someone's faking a leap second tonight

[steven Sommars]

The main standard says a leap second is allowed in any month.  That's what
the reference ntpd does.
See ITU-R, TF460, STANDARD-FREQUENCY  AND  TIME-SIGNAL  EMISSIONS.

On the other hand Bulletin C (
ftp://hpiers.obspm.fr/iers/bul/bulc/bulletinc.dat) says December or June.


Take your pick.
