[time-nuts] Leapsecond on Apple iOS

Fellow time-nuts,

Several friends observed that their Apple devices, laptop and phones, 
did not handle the leap second timely. One recorded the UTC+1h time with 
the sequence

00:59:57
00:59:58
00:59:59
01:00:00
01:00:01
01:00:01 <- leap second inserted
01:00:02
01:00:03

The other dug up that Cocoa claims that using NTP prohibits it from 
implementing it correctly, which doesn't match my laptops observation 
being fed only from NTP.

Anyone else saw something similar?

The hurdles of precision time in a POSIX-damaged world...

Cheers,
Magnus
