[tz] Converting cities to tz identifiers (tangent)

[J Andrew Lipscomb]

For the USA, does city mean the metro area or the city proper? The next five metros in Eastern time after NYC are Washington, Philadelphia, Miami, Boston; for cities proper, it's Philadelphia, Jacksonville, (Indianapolis), Columbus, Charlotte.

Although it's not now clear what that other location would be (it'd depend on what part of the US switches), one candidate would be America/Indiana/Indianapolis. This is because if Jacksonville, Philadelphia and New York all switch to Atlantic time, then Indianapolis could well be the largest remaining city observing US Eastern time. This should amuse those of us who recall the history of UT offsets in Indiana.
