Is time zone ID for Buenos Aires wrong?

[kamorrissey]

I ran into an incompatibility issue that required me to back out a recent fix in a product. We have an Android-based embedded device managed through a Windows Qt 5.9.1 application. The embedded device uses none of Qt.

The device uses "America/Argentina/Buenos_Aires" as the ID for the Buenos Aires time zone. This is consistent with what I see in the IANA TZ data file (at https://www.iana.org/time-zones).

Qt, on the other hand, uses "America/Buenos_Aires" as the ID, which is nonconforming. What's puzzling is that QTimeZone documentation says it uses the IANA TZ database, so I don't understand why there's a difference. I also don't yet know if any other TZs have similar problems.

Does this constitute a bug in Qt?
