No, it appears that a few people think that "the GMT standard" is
synonymous with UK local time. This is just as much a fallacy as the belief
that Indiana currently observes US "Central Time".

And, by the way, the "GMT standard" is *NOT* synonymous with UTC; it is

True. Nor would it mitigate the Indiana problem.

Nor, incidentally, would it harm either.

Apart from astronomers, of course, who actually cares what the value of
DUT1 is? Consider the value DLCT (LCT-UTC). This varies between -1 and
3601 over the year, yet the only effect it has is that it varies whether or
not I have to turn on the car headlights on the way to work.

Yet they cope with the complex proposals to move counties of Indiana
between zones, or to move DST end-dates every decade or so. We coped with
the introduction of British Standard Time and its abolition.

I suggest that fiddling with the hourly shifts will continue every few
years ad nauseam, so one more reason for doing so won't bother anyone.

That works when it works. Not when there are irreconcilable differences in
the "general requirements and objectives".

Within a couple of hours plus or minus.
