How is Google's leap smear idea pretending like leap seconds don't exist? As per your link, "The solution we came up with came to be known as the “leap smear.” We modified our internal NTP servers to gradually add a couple of milliseconds to every update, varying over a time window before the moment when the leap second actually happens."

From the article:

> Usually when a leap second is almost due, the NTP protocol says a server must indicate this to its clients by setting the “Leap Indicator” (LI) field in its response. [..] Rather than doing this, we applied a patch to our internal NTP servers to not set LI, and tell a small “lie” about the time, modulating this “lie” over a time window w before midnight
