[LEAPSECS] Windows Server 2019

[Steve Allen]

as seen on slashdot and more, Windows Server 2019 will support leap seconds.

That blog entry points at several MSword docs for admins and devs, and
https://aka.ms/Dev-LeapSecond
finishes with this interesting warning:

Known issues:
Some frameworks are known to calculate time incorrectly after a leap
second occurs.  For example, the .NET Framework uses its own internal
logic to determine what time it is.  Its logic does not account for
leap seconds.  So after a leap second is introduced to the Operating
System the output of "System.DateTime.Now.ToString()" will be ahead by
one second of the local system time.  (We are working with the .NET
framework team on this.)

In combination with the many steps that it takes to configure Windows
this sounds like there will be some really interesting results.
