These patches make my POSIX conformance side very uncomfortable.
The comments about the data are generally more accurate by using UT.
The comments in and about the POSIX API get very confusing for not
using UTC (as is done in the POSIX docs themselves), and I think they
might best be left referring to UTC.

Unfortunately there is no single good answer for the name of the
Greenwich-like time scale that is presumed by computer APIs.  In the
absence of switching the zdump output string between UT and UTC as of
1960 some sort of apologetic explanation may be required.
