[LEAPSECS] max acceptable rate of TZ fudge/IDL creep

The timezone fudge could be by redefining the offsets or redrawing the
Redefine the offset would likely be at the national or possibly
state/province level (e.g. Newfoundland in Canada or Darwin in
Australia have, or have had, half-hour rather than hour offsets to
the local flavor of their timezones)
Redefine the boundaries would more likely be at a more local level of
county or metropolitan areas (some areas in Indiana or Arizona in the
US, but also the IDL creep recently seen in Samoa)
And as for people handling DST...
I live in Arizona: no DST (except for the Navajo reservation which
does use DST). I have friends and family elsewhere in the country.
I would question that people easily handle DST.
But this would take place essentially everywhere every decade or so,
and on a fairly piecemeal basis.
I anticipate chaos.
