That makes EST5DST correct except for NYC and America/New_York
completely incorrect except of course NYC.
Which is why I prefer to use EST5DST
It may be a valid reason, however
- You stated that you do not care concerning historical timestamps.
- It is still unclear for me for what territory EST5EDT is more correct
than America/New_York or another similar timezone. My expectation is
that America/New_York is accurate at least for New York and
America/Detroit is accurate for Detroit.
- EST5EDT in Debian is extension in respect to POSIX.
- America/New_York and EST2EDT are both provided by the same tzdata
package, so quality of America/New_York is not worse.
- IANA TZ DB does not support timezones disappeared before 1970.
<https://data.iana.org/time-zones/theory.html#accuracy>
- After 1970 these timezones have no discrepancy.
BTW there isn't any timezone called America/New_York, it is or course
the Eastern Standard Time Zone.
America/New_your should actually be called America/Eastern. The POSIX
EST5DST is closer to being correct.
For me America/New_York is just an identifier. Perhaps you do not like
this city for some reason, but for me it has no negative context.
Decisions related to identifiers are clarified in

After all
ls -l /usr/share/zoneinfo/US/Eastern
lrwxrwxrwx 1 root root 19 May 29 2023 /usr/share/zoneinfo/US/Eastern ->
../America/New_York
For most of users I still recommend to stick to names like America/New_York.
I would not neglect IANA TZ DB just because it has usual disclaimer.
Despite POSIX is a standard, I see efforts to keep TZ DB accurate. That
is why reputation of IANA, Arthur David Olson, and Paul Eggert has more
value for me.
