That's the idea—you have to go back to sources, and as you find them,
you check whether they actually took effect (newspaper archives being
a useful source here), and then you make "fixes and enhancements" to
the database, just as you quoted earlier.
As for the choice of "New York", perhaps easiest to quote the Wiki page:
“Location is the name of a specific location within the area –
usually a city or small island.
“Country names are not normally used in this scheme, primarily
because they would not be robust, owing to frequent political and
boundary changes. The names of large cities tend to be more
permanent. Usually the most populous city in a region is chosen
to represent the entire time zone, although another city may be
selected if it is more widely known, and another location, including
a location other than a city, may be used if it results in a less
ambiguous name. In the event that the name of the location used
to represent the time zone changes, the convention is to create an
alias in future editions so that both the old and new names
refer to the same database entry.
“In some cases the Location is itself represented as a compound name,
for example the time zone "America/Indiana/Indianapolis". Three-level
names include those under "America/Argentina/...",
"America/Kentucky/...", "America/Indiana/...", and
"America/North_Dakota/...".
“The location selected is representative for the entire
area. However, if there were differences within the area before 1970,
the time zone rules only apply in the named location.”
Earlier, you wrote: "BTW there isn't any timezone called
America/New_York, it is or course the Eastern Standard Time Zone."
America/New_York is the name of a set of rules in the timezone
database, and we're discussing the relative merits of different sets
of rules, not the merits of the names.
Cheers,
David.
