Sometimes it is civil, sometimes it is military, most of the time
it is corporate.
That is why the "coordination" aspect is important, and why any
sensible OS designer or systemadmin makes sure his computers
fundamentally use the coordinated timescale, and apply whatever
offsets therefrom required by local regulations, geographies etc.
However, as is evident from the tzdata, this does not make the
coordinated timescale civil time for anyplace somebody plunks
down a computer that uses it to keep track of time.
And finally: The reason I react to your mantra about "best systems
engineering practises" is that the time window for that is long
past, and the only realistic hope you can have is to delay the
process by wrap it up in red electricians tape.
We're into politics now and to misphrase a man who knew what he
was talking about:
"Politics is the continuation of systems engineering with
different means".
