|
|
*@summary Verifies that sampled European locales use consistent short time zone names.
|
|
* Originally assumed all European locales had the same short names,
|
|
* but due to changes in time zone data and locale handling, that is no longer guaranteed.
|
|
* This test now verifies that a representative sample of locales (e.g., fr, it)
|
|
* still use the same short names (CET/CEST).
