I am not sure what you mean by "sees", but I cant figure a meaning
that would be compatible with the fact that UTC clearly identifies
86401 seconds on the day the leap second occurs.
If you ask utc how many seconds there are between now, and exactly three
days ago, it ansers 3*86400 even if one of those days had a leap second.
Yes of course that leap second occurs on the day, but utc forgets that
it did.
Just, Wow. That's completely wrong.
TAI does not as far as I know, have a concept of days. It has seconds.
If you want to convert those seconds into things like days, months, etc,
that is up to you.
No, the canonical form of TAI is ydmhms...
So, if we count utc seconds we have
1435733999 1435734000 1435734000 1435734001 ...
Those appear to be POSIX times. They're certainly neither UTC nor TAI.
You keep saying "UTC" when you're talking about POSIX, which naively
tries to keep both epoch (time since...) and wall (UTC) time, and fails
miserably since the two are mutually exclusive.
