No, that's not how UTC works.

Everything Zefram says is what I was trying to say and failing.

I would only add that:

1) TAI-UTC refers to broken-down time, not to the count
of seconds since some epoch.  TAI-UTC is currently 37 seconds, which means
that at 2018-11-05T13:43:00 UTC time (approximately when I am writing this) it is
2018-11-05T13:43:37 TAI time.

2) Posix time, unlike UTC really does label leap seconds with the same integer as the
preceding second.

There is no real going back.  Though I may come to the Shire, it will
not seem the same; for I shall not be the same.  I am wounded with
knife, sting, and tooth, and a long burden.  Where shall I find rest?
