Hi Chuck,

"Linux systems now know about the leap second" -- this is a very dangerous assumption. And one reason why leap seconds have gotten out of hand the past decade.

Just because you observe one tz update from Debian does not imply that all "Linux systems" on planet earth (or in space) magically know about leap seconds. There must be millions (billions?) of embedded or isolated systems -- from web servers to desktops to military systems to gadgets to Raspberry Pi's to mobile phones, that have not, and will not ever receive this update.
