1. America/New_York will always be the timezone for the city of New York, even if it secedes from the US, joins Canada, and goes on Newfoundland time.
Cool idea. That way all other Canadians can hate New Yorkers up and down and sideways, taking some of the pressure off Toronto.
2. America/New_York is a stand-in for US Eastern Time. If New York City secedes and changes, the America/New_York TZID will associated with US Eastern Time.
"will remain", I suppose. No, Philadelphia (as of 1990, anyhow; I don't have current population data) would take over as the exemplar.
And if America/New_York is to be stable, that would, of course, be a huge mistake, akin to changing CS from Czechoslovakia to Serbia and Montenegro. Simply because the city were renamed should have no effect on the TZID.
The TZID would be reassigned with an alias provided. This has happened. However, AFAIK no TZID has ever been reused with a different meaning. -- Here lies the Christian, John Cowan judge, and poet Peter, http://www.reutershealth.com Who broke the laws of God http://www.ccil.org/~cowan and man and metre. jcowan@reutershealth.com
