Well, that turns out not to be the case.  Try "date -d 1943-01-01"
on a system where GNU 'date' is available (Linux, e.g.)  Set TZ to an
American time zone first if need be.

They are not meant to be authentic, and exist because time libraries
are expected to provide a time zone abbreviation even where they
don't really exist.

Rather than making ill-conceived suggestions for improvement based on
uninformed guesses about established conventions in a field of study with
which familiarity is limited, it is sometimes better to stick to merely
observing the usage and listening to the explanations offered, inserting
only questions as needed to fill in gaps in understanding. --Peter Constable
