That quote is not from Microsoft, but rather from the
ION paper by Matsakis, Levine, and Lombardi
That can be got by ION members, or from USNO if their
webserver recovers, or from researchgate if you can
tolerate the javascript that will try to execute
https://www.researchgate.net/publication/323600621_Metrological_and_legal_traceability_of_time_signals

Microsoft seems to be documenting a new mode of OS configuration which
actually does count the second named "60", and specifically in order
that Microsoft systems can say they conform to MiFID II and other
regulatory agencies that demand conformance with UTC as defined.
Otherwise the old default configuration will have a second that lasts
2000 millis.
