Hi, On my two linux-boxes I've got this in my logs: Box 1: Jul 01 01:59:59 [kernel] [11613806.049909] Clock: inserting leap second 23:59:60 UTC Box 2: Jul 01 01:59:59 [kernel] [976439.291563] Clock: inserting leap second 23:59:60 UTC (I'm on UTC+2) That's the only thing in my logs I could

In light of David's report and looking at my own similar Windows ntpd + PPS GPS setup, I retract my nuanced comments about his offset graph, because I now believe ntpd on Windows misapplied the leap second completely. The code scheduled it perfectly, relayed the info on to clients correctly, then

Was it advertising leap=01 before the leap ? It might be because it leaped backwards (would be strange, though : no backward leap was ever introduced in the leapfile, IIRC) 2012/7/1 AlbyVA alb...@empire.org: It looks like my server picked up the Leap Second, but it just counted 19:59:59

Yeah it was showing Leap=01 before. My guess is that it just did :59 twice rather than :59 then :60. I doubt it leap'd backwards, since there was an added second by doing :59 twice. Had it leap'd backwards, I assume it would have gone :58 - :00, thus removing a second of time. On Sun, Jul 1,

[Pool] Worried about leap second and UUID

Hi, Many systems still generate v1 uuids ( http://en.wikipedia.org/wiki/Universally_unique_identifier#Version_1_.28MAC_address.29 - for example still used by MySQL by default ) and seeing how most OSes are handling the leap second is kind of worrying me, since it greatly increases the risk of
