Irjak, hogy a fo oka a szokomasodpercnek a sarki jegek periodikussaga, de a kozeljovoben ez akar -1 masodpercet is okozhatna. Naluk eddig is elnyujtottak 17 orara azt az egy masodpercet:
"More recently, it has become a common practice to “smear” a leap second by simply slowing down or speeding up the clock. There is no universal way to do this, but at Meta we smear the leap second throughout 17 hours, starting at 00:00:00 UTC based on the time zone data (tzdata) package content."
Kulonbozo GPS variansok is a sajat munkarendjuk szerint iktatjak be a szokomasodpercet, ami miatt diszkrepancia van a rendszerek kozott. Pl:
"Back in 2012, Reddit experienced a massive outage because of a leap second; the site was inaccessible for 30 to 40 minutes. This happened when the time change confused the high-resolution timer (hrtimer), sparking hyperactivity on the servers, which locked up the machines’ CPUs."
Szoval van baj is a szokomasodperccel, persze lehet csak a rossz/kenyelmes implementaciokkal, a koordinacio hianyaval.
